Honestly I'm still overwhelmed by the amount of woo woo here. Maybe you could say I have a 'spiritual' or philosophical Outlook and sympathy, but I can't imagine that I would ever subscribe to the kind of irrationality some of you seem to go in for.
However, I do like to hear some of the wilder theories and find that kind of thing generally interesting, as long as there's some plausibility and internal logic to it. So don't think I'm being critical here, I just mention it to point out that it's not something that I identify with as an INFJ. I do, however, suspect that's it's a natural reflex in me (I.e. There's a conflict between what my 'heart' believes and what my 'mind' believes).
Anyway, on the topic of dreams:
I read an essay or two of Jung's in Modern Man in Search of a Soul, and his point about dreams really isn't complicated. They reveal the workings of the unconscious. That's it. There's a gloss over that about universal symbols, but even this is perfectly reasonable; it's not mysterious or magical.
So what dreams do I actually have?
My first love died in a kayaking accident, and I had a dream that felt powerfully real where she was 'alive', but not necessarily 'in the world'. We were together, conversing, &c. That's the most impactful one I've had.
I am sometimes woken by dreams about being crawled upon or seeing giant, spindly spiders or webs. I'm not afraid of spiders.
Mostly, however, I've got to admit that my dreams are about sex or cuddling. At least those that I remember. Yeah I dream about spooning, not the apocalypse. Dull I know.
I've had really serious conscious existential terrors or dreads in the past, however, so maybe there's no reason for dark thoughts to manifest in dreams, as I tend to confront these thoughts in the real world.
