Could the whole thing have been a dream?

Even if you remember waking up before it happened, that doesn't mean that it was not a dream. You can have a dream within a dream, or have two consecutive dreams that make you feel like you dreamed within a dream.

It definitely could have been a dream. It was a strange combination of the physical sensation of floating and falling, but also observing myself in the third person that was very unusual.
