The number of dreams that occur in the world on any given night would number well into the billions and some of the most ancient writings in existence attest that people dreamt (and were just as puzzled by what they dreamt) since writing began. In dreams we are all schizophrenic:
-You’re in your first grade classroom and you know absolutely it’s your first grade classroom except now it’s a Starbucks. All of the kids from first grade- including some you haven’t thought of since first grade are there, though you’re the age you are now, and you never noticed before that your first grade teacher has wings (like a butterfly, though, not like a bird or an angel). Mussolini and Aunt Bea are having sex up against the wall and nobody seems to notice, and for show and tell you’ve brought a perfect miniature swimming pool complete with live miniature swimmers, all of them alive and seemingly unaware that they’re in a little glass bubble you wear around your neck, one through which you can also see Dayton, Ohio (and sometimes Lima, Peru) if you look through it in the right way. The bell rings and you think “shit, that means Mrs. Moorehead’s desk is going to turn into a burning futon” and sure enough it does, and it makes perfect sense- why shouldn’t it turn into a burning futon?"*
Or, perhaps, you might even think in the dream itself “this is screwed up… wtf is going on?” But at the same time it’s also very real- you can hear Aunt Bea grown with pleasure at Il Duce’s every thrust and you can feel the water on your chest when the little mini swimmers splash it through the little ocular at the top of their glass sphere (they think it’s a sun), you can smell the smoke from the burning futon. Weirdest of all is when you take home a souvenir from the dream, such as waking up and thinking “Susan Dietrich… sat about two desks behind me in Mrs. Moorehead’s class… her mom had a big mole on her face… her family was military and moved somewhere in the middle of second grade… I haven’t thought of her in 25 years, was never friends or enemies with her… and yet there she was. Where’d that come from?” (Assume for purposes of this writing that Susan Dietrich from the dream did exist in your real first grade class- I’ve definitely had things like this happen [sometimes with people, sometimes with inanimate objects or a long forgotten detail like a snag in a rug at your grandmother’s house or the name of a babysitter’s dog {Snowball, who’s been dead for 35 years or more but who licked my face in a dream recently}).
The crazy thing is that nobody really knows what a dream is. There are hypotheses ranging from the mystical to the just plain silly to the scientific; we can monitor a brain’s actions during the dream state, we even know that there are different kinds of dreams. We’ve all felt ourself jump back with a start in a dream, we’ll talk out loud in the waking, sometimes you might even feel your teeth falling out after you wake up before you realize “twas a dream… they’re just find”… whatever, and there’ll even be bleedover from the Waking into the Dream (Anderson Cooper narrates it talking about the same bedouin camp he happens to be visiting on the TV which is on even though the dream takes place in a grocery store). But we’re no closer to understanding dreams now- really- than we were 4000 years ago- “Why did I see Susan Dietrich who I haven’t seen or thought about in 30 years? Why did Mrs. Moorehead have wings- and like a butterfly and not an angel? Why was the first grade classroom a Starbucks and what in hell made my inner porn director say “Spinsterly asexual plump TV icon, get over there and do it with a mid 20th century European dictator” (and why Aunt Bea instead of Alice the Maid or Aunt Clara and why Mussolini instead of Tito or Franco?).” We have absolutely no idea how these images are chosen, what their significance is (if any), or even "why’d we have this dream last night instead of the mundane ‘I can’t find my car keys and I need to get to class’ dream that’s so boring it could actually happen.
I find it very hard to express what I want to say… somehow I think dreams and ghostly perceptions are related. That’s not to say that I think dreams are real- I honestly don’t think Snowball really licked my face recently- or that I think all ghostly encounters (for lack of a better term) are hallucinations exactly (though I don’t discount for a moment than many, probably the vast majority, are). But I do think that whatever it is in our subconscious or our various “cranial wrinkles” that sometimes allows us to pull up Snowball/Susan Dietrich/that snag in a carpet you haven’t seen since childhood also makes us perceptive to something… out there… that might actually be out there but not usually… perceptible.
This is sounding way more X-FILES and Deepak than I mean it to or than I am, but I do think the mind is a fascinating thing that can sometimes, as we all know, perceive patterns even when there’s no pattern there and we have to supply it (i.e. there’s nothing intentional about that tortilla chip looking like Don Rickles), but there are also times when we perceive an order that is there (of course Susan Dietrich was in the first grade class because she was in real life, and even though we haven’t thought of her in 30 years she’s zapped into the dream). I am not explaining this well at all (weird subject on little sleep), but I think sometimes we’re more perceptive than others.
But I still think professional psychics are 99.9% bunk . (There are a couple of people I’ve known who I do believe have some mild psychic capabilities- one gave me and my mother some advice of sorts that was incredibly specific [not cold reading but a “there’s a book here that is marked with a check…”- well, long story] way in advance of lucky guessing or “remember the hits/forget the misses”- but both hated the ones who charge, claiming “it’s not a water nozzle I can turn on and turn off- I get absolutely nothing when I try to get something”.)
OTOH, one of them was also into astrology which I think is slightly less a science than the writing of fortune cookies, so… c’est la vie say the old folks, goes to show you never can tell.
*This isn’t a dream I’ve actually had but more an excercise in random name and summoning and placement.
