Yeah, what happened if it is all of a dream? your senses are being play into duping you into reality, like the "Matrix". Senses like smell, sight, hearing, touch are all stimulate. While you thought you were doing physics experiment handling data and coming up with laws and theories, it was just a dream.
"But we're all saw it." "It is on data, we videotape the whole experiment." "I did it myself." "You were there, weren't you."
That's what happened to some guy that did the cold fusion experiment.
