You can't say 'we' as not all of us live in meaningless daydreams of egotistical desire. You can only speak for yourself and your own torment and pain.
So for you it's a fleeting escape and the realisation that there are perhaps other realms brings you solace?

You say those 'realms and their wisdom' are aspects of a greater self. I won't ask about those realms but I'm interested in wisdom. How do you know they contain wisdom? Did you read, hear or see something wise?

I'm guessing no and you haven't experienced anything at all. You come here and make a claim, really just fulfilling your own meaningless desire and you can't even see that lol.

Its perfectly wise to be highly skeptical of these things.  I certainly had no faith in religion or believed in the spiritual at all.  But I had enough curiousity to check out certain claims for myself.  Yet I remained highly skeptical even when experiencing what I would call supernatural experiences back then.  Checking if I was delussional or not .. it cannot be but it was. Yet there was some kind of familarity to it all like being home again!.  Today I believe that there is perennial wisdom in all the religions that anyone can experience if they have the will and desire to do so.

Yet there is also a danger in desiring supernatural abilities.  The ego-construct can achieve certain abilities but those abilities come at cost (yes I got burnt).  So before venturing in the supernatural you really need to question why you have desires to do so. If its for ego I strongly suggest not to bother. As for wisdom. The universe itself is the unsegmented mind. It has far more capacity than our puny segmented local mind could even imagine.
