if you had psychic powers and you could just walk up to someone, know their name, and what was going on in the day and say in the most calm and sure voice ever, "Donna...none of this is real. This is all a dream, Donna. Soon you will wake up and realize that your credit card was not stolen".

Idunno I just woke up and thought of that. That would be hilarious. Especially if you encountered a lucid dreamer. Haha.
