So last night, I had a pretty intense vivid dream. During one part, everything seemed quite realistic but also, transparency?(not sure how to describe the feeling). Anyway, during one part, I touched a guy in order to see if he was real and for some reason, I did my reality check(I think, it's kind of hazy) and I think I realized I was dreaming. After that, I think I got super excited or something and the next thing, I knew, I woke up. Was this a LD?
