there is a fact that all people have many dreams in one night. there is also a fact that people do not remember all or any of their dreams. is it possible that there is a constant shared connection and these "DC" that we see are just people on another side of the world. an expieriment for this would be to have two lucid dreamers that recall almost all REM states. they would have to be close friends. if they could recall all dreams there is a possibilty that they will have similar interactions and give some evidence of connection. i say this because when i see people i know in dreams i think that on some level they had a similar thought wether it was subconcious or not. my theory is that subconcious minds are all linked because well we really do not know how the subconcious really operates.(as far as i know)

if theres some psycology buff that wants to expand on this feel free im sure im not the only one with this idea. if i am and u get famous i'd like some credit
