The On-Off Tap of Dream Activity

[anagogy]

What I mean by caused by another: I watch all of the paranormal witness episodes & I've noticed it's very common for someone's dreams to be affected when they move into a house that's haunted so I've concluded others can be the cause of our dreams. When someone I don't think twice about gets in my dreams I usually suspect it's somehow their fault that they've managed to get in my dreams.

I've found (and this is simply my opinion based on my personal experiences) that we will often dream of others who are mentally dwelling on us heavily.  I didn't make the connection for a long time, but I can actually feel this in my waking state to lesser extent, and can oftentimes feel when somebody is really thinking about me.  I've even texted friends whom I felt doing this and asked them matter of factly why are they thinking about me (which they then confirmed).  I've learned not to do that, though, as people tend to find it a little disconcerting.  Idle thought doesn't register usually, but heavy thought feels to my perception like they keep entering my thoughts, and it is completely out of character to what I was thinking about.  So anyway, I believe subconsciously we always register when someone is thinking about us, and it often spills over into our less analytical time/space experiences at night (or day, for you vampires).
