One of my most recent LDs was caused when a DC ran past me saying “What are you so worried about? It’s a dream!” 
(I was stressing because I had unintentionally killed two IRL friend DCs in the dream)
My very first LD was caused by a conversation between an IRL friend DC and me, though I did come to the “I’m dreaming” conclusion by myself.
DC can be so funny. And yet so helpful.
