What do you say to someone you meet whom you recognize from a dream? Hey, you don’t know me, and this is going to sound weird and uncanny but…I think you were in my dream last night.
Douchebags of the world have killed everyone’s credibility for sincere and mystical stranger moments, so when it’s actually true, people never take you seriously.
I usually don’t say anything. Just wait. And if they approach me, I pay attention.
