Hi i don't know if obe's real or if astral projection is real or even lucid dreaming. But i know what i have been experiencing since i was around 10 years old is real.
One experience i've had is that i had loud ringing in my ears then once it stopped i looked around me and everything that was around me looked the same as i did before i fell asleep. Only thing that was different is that somethings like my wife for instance looked a little different but one time i looked at her and she was faced the opposite direction i was facing then i touched the back of her head then she turned her head, then when i came back out my dream state her face was facing me. Another time my wife my son and i were really tired so we layed down and i fell asleep. I got the loud buzzing in my ears again. Then i noticed i was saying who am I? Over and over again. Then i could hear my wife's voice saying a different name then what my name really is (well the first name was different but the last name was the same.) After that some how i was floating above my neighbours ceiling looking down on them. A minute later i was awake again. After anyone time any of this happens when i come back i feel so afraid that i can't go back to sleep right away i have to fight my sleep till i can't anymore.
