I am a relatively new (about four months) meditator.
My meditation technique is closing my eyes and focusing on the sensation of the breath as it passes in and out of my throat. Today I was meditating for 30 minutes and, as often happens, I saw swirling lights in the darkness of my closed eyes.
As I became more deeply focused on the breath-sensation, the lights went away and there was darkness, but the odd thing was that the darkness extended - it seemed as though I was looking down an endless, dark hallway rather than just looking at my eyelids.
As I noted this, I started to see a purple, vibrating orb appear. I remember thinking to myself that maybe I was about to have some kind of mystical experience. I became a little excited about this, but all of a sudden the excitement morphed into an incredible fear. My breath began to come in gasps and was shaky, and my heart was pounding. I eventually managed to calm down, but wow that was strange.
So my question is - has this happened to anyone else, and is there a reasonable explanation? I have always had issues with anxiety, so I wonder if that is related to this experience.
I have heard that meditation can be harmful - is this a sign that I should refrain from meditating?
