it may be because i recently saw this seinfeld reboot:
your brain works like that; i've read freud, but the truth is that he was pretty much completely wrong about dreams. i like his ideas, but they're just not correct. rather, your brain tends to take random images of things and scramble them up in ways that have more to do with bad error-correcting than with any deep delve into your psyche.
my brain saw "george and jerry at the diner" and it seems to have triggered "dad and i at the diner". it just pulled out the wrong file; random error, nothing deep about it. so, i dreamt about one thing because i saw another, and my brain made a mistake in processing it....
the dead only exist in our dreams, and they exist the way we want them to. so, anything that was said was what i decided would be said; i'm clear on that much at least - this was a conversation with myself, not a conversation with a spirit of a lost relative. he only appeared to me in the form of a projection of my own mind; as real as dreams can be, sometimes, we write our own scripts. ok, maybe there's some room in there for freud after all, even if the dreams themselves are merely randomized error...
i actually don't dream about him very much at all.
i'm awake, now, and in the realm of the living. for now. i'd like to try to enjoy that as best i can, rather than dwell on the past.
don't overcheer, though - it's annoying.
