never had this happen to me, but i wish it would
i know DCs aren’t real, but they do seem real…hey why not fall in love right? its really all in how you view your dreams really. maybe not fall in love, but i would like to meet a DC and have them come back in another Lucid dream and talk to them, DCs are a part of your subconscious mind, a part of you that you can’t access while awake much, but while in a lucid dream you can get to know yourself better. maybe falling in love is a bit much (although i wouldn’t mind) but just becoming good friends with a DC would be nice, and if your good at dream control you can have them appear again in another dream and continue getting to know them. my opinion is, perhaps DCs are a lot more complex and interesting than we think? our minds are surely very complex and interesting, i find it fascinating that our mind can make a world seem so real when its not real.
in a way maybe it is real, even though its not physically real, its real in a sense you are experiencing it, you feel it, see it, and so it can be real in a sense. i would think getting to know your DCs would be a good idea and quite interesting
