I can't think of either, so I'll just describe my last two. Last night I had a dream where I discovered a new glitch in Pokémon FireRed. You could talk to one of the NPCs that moves you around, then take control of that NPC at the end. Then the game would become extremely slow and all the other characters would be replaced by Red.

The night before that, in my dream I was tricked by a nonprofit into taking a month-long vacation to Denmark that I thought would just be a day. When I woke up, there were a few seconds where I actually believed I was still in Denmark.
