Thank you, Ted. I'll just keep on chugging then!
Does point consciousness feel similar to falling asleep? When I listen to Tom's binaural beats I feel like I fall asleep for a short period of time. Not sure if im sleeping though. I also heard that his binaural beats changes frequencies so that you don't fall asleep. I usually listen to them lying down. Maybe I should try sitting up?
I think it is difficult to define point consciousness as a state because people experience different things during meditation. This is apparent when you try to research terms such as samadhi, turiya or transcendence and the various conflicting definitions for each.
What you are describing is a common experience for me but it is happening less as time goes on. Typically, after about 5 minutes, the dialogue in my mind goes quiet. My body is usually very numb and outside "disturbances" are ignored. I am aware that I am having no inner dialogue and it is usually at this stage where I get a LOT of conscious vivid visions which I can not make sense of. Also, sometimes I get stuck inside a story and I get so immersed in it that I start laughing but I am only semi-conscious at that point.
The "blackness" in front of my eyes tends to become 3D-ish and is usually accompanied by a white swirling light in the middle. Something usually tends to happen if I focus on it in my mind but my physical eyes tend to interfere and move, bringing me back.
I think the main indicator though is a silent mind. If you get to the point where you stop talking to yourself and your thoughts then you are just there in stillness.
From my limited experience, it is best to just keep practicing and you will feel differences as time goes on.
