I have experienced several instances where I dream that I am with some friend/colleague/etc e.h. helping him solve some problem. Upon waking up, I check my phone and then sure enough that same friend has in fact contacted with the same or similar message as in my dream.

In several instances these are people I haven't heard from in a long time, with some very hard to guess specific reason why they contacted me. (E.g. a long time friend asking me to help his dad with something).

My memory is very clear that I had the dream and processed it (with some reaction of 'huh strange, fancy dreaming about that guy) before I opened my phone and found the text/email from that person. But is that memory being rewritten somehow afterwards?

Or is there perhaps some kind of vaguely wavefunction/quantum/etc phenomena that leads some information to be transmitted back in time by a few minutes? Hard to say, but definitely food for thought
