Buddhist meditation is not clinging to (i.e., not getting infatuated about) experienced phenomena.
Last year I experienced samadhi, full state of awareness. Mind's
thoughts stopped for days and I can't describe with feelings and words
the complete experience.
This is a type of samadhi. Samadhi is the absence of thoughts, just like an orange is orange in colour. Why are you making a bid deal about something that is totally normal?
Samadhi is the absence of thinking therefore why have you now engaged in a path that is totally the opposite of samadhi, which is thinking about samadhi rather than dwelling in samadhi?
It was like the wheels of my mind stopped. I was living the present
moment very loud. It was like I was standing on top of my head and my
conscioussness was dramatically expanding.
The thinking of the mind stopped. Consciousness expanded. This is normal. But now the wheels of the mind have started up again by asking these questions.
I wasn't practicing anything and I had no idea what it was until
someone who was in the same state since his birth explained to me.
I think anyone who believes they have been in samadhi since birth is probably crazy. I would ignore them.
Before come to this, a few days ago I had some scary lucid dreams
with dream paralisis.
Dreams are just mental fabrications. In sleep, spiritually, changes of consciousness can occur due to changes in neurology. Whatever happened is just ordinary. Nothing to be infatuated with.
I've seen light in the dark. And it was not coming through my eyes.
This does not matter. What matters is to view all experience with equanimity & non-attachment.
The experience of samadhi lasted a few days and it had a curve and a
peak. I felt like the third eye was openned. And I still can't believe
that I'm talking about all these things.
The impression here is of reading too many books & imagining too many things. If the mind really had samadhi for 3 days, the mind would be calm.
Did you take drugs?
In it's peak I felt like I was living in the moment for first time in
my life.
Again, reading too many book, maybe by Eckhart Tolle.
There was no past or future, it was just now.
In reality, there is no real past & no real future. Why are you flabbergasted over what is real?
And everything was so calmful and alive... and there was nothing to
worry about.
Your mind does not sound calm to me.
And I knew that I could be whoever I wanted to be no matter what.
Yep... as i suspected, reading too many books or listening to too many gurus.
Like I was in deep sleep since I was a kid and I finally woke up.
If you woke yup, why are you asking these questions on the internet?
I knew that I could change and improve and manipulate my body and my
mind like a toy.
If so, what are you not controlling your mind, now?
No skills, no title, nothing was impossible, it was just a matter of
choice.
Wow... you sound brainwashed by some new age teachings. Again, if you could do the impossible, why are you here asking these questions?
I felt like everything including me were connected.
You felt like you were Jesus Christ or Sai Baba, it sounds like.
It is difficult to describe exactly how I felt... but It was like i
could feel the vibrations of everything around me from a distance. I
could hear high frequencies when someone was focusing in me. I could
see green auras orbiting in the air.
The "I", "I", "I", is getting tedious and unrelated to Buddhism. There is a Hindu forum you can ask your question on, if the mind is unable to give up delusions of "I".
I was looking the world outside and everybody was like zombies of
their own minds. And I realized that I used to be like them too.
But now you are the next Messiah & World Saviour? Now you will write books, make videos, be a guest on Oprah and have thousands of zombies follow you as your disciples?
Everything was so clear and easy to understand without thinking at
all, like in Limitless movie.
If so, why now without understanding?
It was like I was sleeping in my entire life and I finally woke up in
the real world.
You sound confused to me & lacking peace. When my mind 1st experienced peace in meditation, it remained peaceful after that. I was amazed peace actually existed because previously I felt there was no such thing as peace. Meditation was about "peace" to me rather than about "awakening". I think you have been reading too many books or listening to too many gurus. When the mind knows peace, it remains dwelling in that peace & that peace is a functional (rather than dysfunctional) state.
Everything was so real... I had no good or bad feelings, no thoughts,
just consciousness in an epic level I didn't know that ever existed.
The infatuation currently occurring to your mind shows your mind did have good feelings, otherwise you would currently not be drunk on whatever experience you imagine you had.
I was looking the trees, the birds and the fountain like I had never
seen anything like this before. And they were stunning.
If they were stunning, there was good feelings.
No word was coming in my mind, no thought, nothing. But I could easily
participate in a high quality conversation without using my mind at
all. But I didn't want to talk, I just wanted to listen. For first
time in my life I wanted to listen... ONLY!
So what?
But I had my senses increased at 100000% and I felt my body and my
mind like a cheap version of my real self. I felt my body like a human
avatar for my soul. I was not sure about god etc... till then. I
realized that everything is much more than we understand.
As I said, reading too many books. Avatar & soul are not related to Buddhism.
My body and my mind was like a toy. On top of my head with a distance
of the physical body was my new self that could easily manipulate my
physical mind and body just by desire.
Mentally, you currently appear unstable; sounding like you believe you are the many manifestations of Krishna or Brahma.

So... what was it, where it came from and why? and last but not
least... what's next?
Why don't you ask your friend who has been in samadhi since birth? Otherwise, if you wish to practise the Buddhist path, simply let it all go; simply stop clinging to whatever experience the mind had; which means giving up all of the "spiritual materialism/egoism" that is currently occurring. Whatever was experienced is the past and the past is now over. Remember, you claimed there was no past. In Buddhism, if a beneficial mental state cannot be maintained then it is worthless.
In summary:
Samadhi (lucid unified consciousness) occurs when the mind stops thinking & lets go, which can occur in formal meditation, spontaneously or when people take drugs. That is what it is & that is what it came from.
In Buddhism, what is next is always the Noble Eightfold Path, which is based in abandoning craving, attachment & manufacturing egoism towards every experience without exception. What is next is Nibbana or Peace.
What is not next is believing: "I am God", "I am World Saviour", "I am Awakened", etc. In Buddhism, what is next is not "I am". "I am" is a belief found in Judaism, Christianity & Hinduism but not Buddhism. Buddhism teaches "anatta", which means "not self". The Buddha taught:
The eye is not yours: let go of it. Your letting go of it will be for
your long-term happiness & benefit... The ear... The nose... The
tongue... The body... The mind is not yours: let go of it. Your
letting go of it will be for your long-term happiness & benefit...
Whatever arises in dependence on mind-contact, experienced either as
pleasure, as pain, or as neither-pleasure-nor-pain, that too is not
yours: let go of it. Your letting go of it will be for your long-term
happiness & benefit.
