I've done some hallucinogens in the past and know what they feel like and no matter what I touched nothing brought me out of it. When I dream(i think try are dreams) I am constantly touching my surroundings and it all feels real. Even pain is real. There's no difference in feelings only difference in usually what happens. I know zombies and aliens as giant praying mantis aren't real so that's dream. But then there's the other stuff that is so real and causes physical pain. Almost as if my dreams become real. The memories are there the feelings and pain. Yet they occurred while I think I'm asleep.
