My first lucid dream was years ago, but the sign was quite.. vague..specially compared to everything else.

Lol, okay I was in a purple room, with people who where floating, furniture was upside down, I had talking fish, the doors who have conversations with the pictures, and a bunch of other wierd things.

Strangley, I thought none of this as wierd.

I was then floating around and noticed I was wearing a white shirt.
I never were white shirts, and thats when it became lucid.

When I woke up, I was just like... did I seriously figured out I was dreaming by that?
