Just today i was awake sitting in bed because i could not fall asleep due to my insomnia so i decided to meditate. Well because i live in a noisy college dorm and all the other students happen to be waking up and making loads of noise at the same time i decided to look hook up my ear phones and listen to some binaural beats while i meditated. And then i noticed a second problem, over the last school break they installed a spotlight right next to my window to act as a street light type device for the side walk that runs along the outside of my dorm building. So i decide, "Hey why don't you try ganzfeld again". So i make a quick light diffusing device, i.e. i tied a white t-shirt over my head so that my entire field of vision was red, and i play the binaural beats sound along with some static as i usually do when i meditate. I put a red screen on my computer and i started to meditate. This is an account of my techniques and what i experienced.
-At first i start to get my mind settled so that i can focus on nothing but the task at hand. This usually takes about 5-8 mins.
-once this is accomplished, i focus on trying to focus both of the sounds i'm hearing into separate sounds, but at the same time focusing on both of them. Its hard to explain but its like those puzzles that are actually 2 different picture and your mind has to switch between them and can only see one at a time, what i do is i catch it while it is switching and concentrate on staying there. This usually doesn't take to long as i have done it many times before. I stay here as long as i can.
-After a few minutes in this position, i start to feel pressure on/in my head where it is often claimed the third eye is. I now try to focus on that also. After a while, the pressure becomes more intense and i start to get slight closed i visuals when i close my eyes.
-This is the part that was different than normal. As i focused i started to feel my eyes tremble. I become scared because i have never really felt this feeling. Soon it starts to spread to the pressure in my forehead. I feel it slowly creep to the rest of my body down my neck and into my extremities. And after a while the slight tremors become a shaking, not a violent one but i can feel my bed moving. I am really scared at this point and decide to hold on to see what would happen.
-I start to see this tunnel like thing forming out of the blue/purple things you would normally see when your eyes are closed to tightly. At this point i feel myself "moving", like i feel the sensation but i know i'm not going anywhere. I see the tunnel moving past me and in the horizon i see this place like a city of glass, but it has this rainbow like luster to it. I want to badly in my heart to go see it, but this voice tells me that i am not ready and then the tunnels takes a detour away from it and leads me into a dark pit. Its like i can feel myself entering my self if that makes any since. Then i lose the visuals. But i can feel the area where pressure is reverberating. and it spreads through out my being the same way the shaking did. then i start to "feel" the air around me doing the same thing.
At this point i decide that my meditation is over due to the fact i must ready myself for class. I take the shirt of my head and i feel like the room is still reverberating. Everything around me has this strange glow about it and i feel a bit shaken but completely at peace and ready to take on the day.
I really just want to know if anyone else has ever experienced anything like this, or if they have tried this meditation set up before. Any input will be helpful and appreciated.
