Hello,
My name is Avicus. I've recently stumbled upon deep meditation and practice deep breathing techniques to reduce stress.

I had a very strange experience while practicing deep breathing and I suppose meditation. I've only been doing this for about two weeks. About 50 minutes of meditation one night in a dark room with my eyes closed, my room illuminated with a green glow before my closed eyes. I saw everything in my room and I waved my arms in front of me and I could see everything. I opened my eyes and the illumination disappeared, when I closed my eyes again I could no longer see the lights or my room. I tried to meditate once again in hopes of seeing the same thing again but I was unable to. Shortly after I started to experience a spinning feeling. I lay there still breathing but the spinning got really intense and for some reason I was filled with fear, so much that I had to pull myself out of the meditation.

It's been about week since I last experienced that and I have been trying to repeat it since. Last night I went into a deep relaxation and tried to meditate however, I decide to lie on my side after awhile thinking I might as well just get some rest. Almost immediately after I felt as though the room was spinning, realizing that this was what I was hoping for I remained calm and re-assured myself that there was no danger and that I was just going to let it flow. It felt as though 10 or 15 minutes had gone by and the feeling got really intense. I felt something like webs latching onto me, pulling me towards the ceiling I opened my eyes and I could see that I wasn't moving however the feeling was still there and intensified. I tried to remain calm however fear overwhelmed me and i came out of it, but it was not as easy to come out of as my last experience. My body felt really heavy and it seem to take all my strength to move it.

I am a healthy individual and I take no substances. I do yoga as an exercise and accidentally came across meditation during a session, meaning I experienced calmness of mind, feeling fully aware of my surroundings with no noise in my head at all, no irritating thoughts or feelings.. just aware of breath and body. After experiencing this wonderful feeling I decided to look it up and came across breathing techniques, belly breathing. All this is new to me and it's really changed me, however I don't know what to think of it, am I losing my mind or is there something real about this?
Does anyone have any idea what I've been experiencing?
