false awakening

I wake up, and sit up in bed, as if to get up. Something makes me hesitate. My room should be dark, but it's lit up slightly, with a blueish light. I feel off. "I could be dreaming," I think. "I can fly!" I tilt my head back and imagine myself lifting off my bed and I float up towards the ceiling. The ceiling seems to waver, as if it isn't actually there, and I think to myself that I'll fly right through it and outside.

The dream either ends or completely changes at this point. Can't remember anything else.
