Ever felt like this?

So ummm, I have this wierd feeling, I get it when ever I want, and I’m feeling it I can make it fade slowly any time I want… I call it the “real” feeling… … And I don’t know how to explain it!!! It’s undiscribable!! Suddenly I start seeing things around me as if I’m looking at them with someone else’s eyes, I think of them as if it’s the first time I see them in my life!! And I start touching things around me, as if I’m touching them with someone else’s hands, if I’m in bed, I see myself laying on it from the top, as if it’s someone else looking at me from the cieling… It’s really weird,,, I start thinking deeeply, as if I’m on another planet, in another world of mine… When I’m normal I just look at a glass of water as a glass of water!! But when I’m looking at it while I’m feeling this “real” feeling I feel like it’s a real glass that has water in it, and the water was in the bottle, the glass was in the sink, it was washed and the water was pored in it from the plastic bottle, and the bottle was in the fridge, we took it out first of course, the fridge was closed we opened it and took the bottle, … never ending, ever lasting… And that’s how I think of everything when I’m feeling so “real” What is this feeling??? I feel like I’m someone else when im’ feeling so “real”!!!
