So... last night I'm in the middle of a dream when I begin to suspect that something isn't normal, so I decide to perform some reality checks. They all failed.

I couldn't breathe with my nose closed, I couldn't fly, my hands looked fine and I could read perfectly too. The other thing; asking yourself 'how did I get here' also failed. I stood there for ages trying to think what I'd done that morning or the day before, but I couldn't remember. This didn't make me lucid at all, it just made me confused as to why my memory was so bad. Figuring I wasn't actually dreaming after all, I went on with the plot of the dream none the wiser.

I guess sometimes dreams being so realistic is a problem for becoming lucid
