Weird feeling, like i saw my room with my eyes closed
Hello!
Last night i went to bed and was quite tired. I was thinking of random things and after 10 minutes something happened. I actually saw my room with my eyes closed, the light was on although it was off. I did not realize that i'm seeing my room, but then all of sudden i realized it and it scared me bit and i opened my eyes. Everything seemed so real. It was quite odd experience but since i was so sleepy i tried not to think of it and tried to get some sleep.
After few minutes i saw my ceiling and again after few moments i startled and opened my eyes.
I got up and got myself some water and just sat on my bed for a while and after that i was able to fall asleep normally.
My question is, what the heck was that? Did i entered LD or something or was it OBE? What should i do if i ever experience that again?
Thank you!
