dreams have equivalent place in reality but sometimes things appear different.
like there's a lake on one place while in the dream there's none.
and from my experience the entities within the dream have mind of their own.
it was proven by someone in my dream making a very clever joke which I only understood later that day.
there's also a chance that you can elicit new (or ancient) information from within the dream.
usually it's all about brain wave state but I'm no master to be able to access the custom dream hubs yet.
was able to elicit some kind of word which pertained to this object. never heard of that word before.
and looking it up on the internet it was some kind of language and the translation was spot on.
maybe it was since I was about to wake up when that happened.
during the wake up sequence I tend to get a lot of information, sometimes unusual or familiar ancient scripts, and other symbols that look like sigils but complicated but I never understood what those were all about and it only happens when I dabble and focus on the occult.
I'm not really consistent, though have to some degree some ability. viewing remotely, or synchronicity but the latter is somewhat dangerous I think since it affects physical reality so much (while it requires my will to be stable since it almost gave me schizophrenia). trying to focus on affecting dream reality now since I think it's a lot more stable to tamper than the current (shared) reality (which has risks of schizophrenia).

I can say I've been sick few times in the past few months/years and the effect was some kind of ego death or urge to be "decent". I'm not the most decent person in terms of sexuality since I may have delved too deep and tampered with or awakened the wrong chakras or maybe it was essential for energy manipulation but maybe since I'm the kind who "does not read the manual" and just focuses on the immediate results.
also I don't think if I should be glad or the opposite now that I barely experience deja vus. at least I don't get those existential dread from when it happens.
