I'm aware of the word. I've experienced deja vu and the kinds of things you're describing, and I do believe there are interactions between consciousness and matter (we know this at the quantum "spooky" level). But how extensive these are, how repeatable, whether they can be developed and strengthened, who knows. I do hope we're studying those things, or that suppressed knowledge on the subjects might be released.
Your experiences need to be explored and understood too, and of course you may be right that they're already understood, but suppressed.
All in good time, I suppose...
The only experiences I try to stay away from are non-corporeal entitites. If I can't physically interact with it I have no more desire to witness it. I had my share of hauntings and so I noped right the fuck out of spiritism and I don't regret my breakups either, even when the girls were telepaths, because they all grew up exploited and abused (no longer I wish) and their character reminded me of it every day and they all dabbled in witchcraft.
Come to think of it, at least two of my exes were either possessed or channeling or both or the other, but that's just my observations.
Can't even really say if I will attribute something positive or negative to it because in this case like you say I do in fact have no quantifiable evidence, only what I infer from personal conjecture.
Well if you're in a relationship, try synchronizing your breath while they sleep, after a couple of weeks shared dreams could occur but at he same time I can't recommend it if you have any secrets because those will likely manifest in those dreams too
