When I first started paying closer attention to my dreams years ago, and their vividness increased sharply, I was scared to let it go further. I was fine with the idea of becoming lucid in a dream, but I was terrified of confusing reality for a dream. I wondered what would happen if I did something like jump off a building in waking life because I thought I was dreaming.

I let go of that fear pretty quickly, because I realized something reassuring. I almost always think I am awake while I'm dreaming (the definition of a non-LD dream), but I have NEVER thought I was dreaming, and then realized later that I was really awake. Of course I've said, in waking life, "Wow this is strange, I wonder if I could be dreaming?" But that was just a passing thought, never a true belief that I was actually dreaming.

Have other people had this fear? Does anyone ever really mistake their waking life for a dream?
