One thing I wanna add is that psychedelics can suppress the ego
temporarily and put it in its place so to speak, allowing you to see this different view - feeling like a meta-perspective, sort of dissociated or hyperassociating... hopefully you know what I am talking about.
The phenomenon called enlightenment (especially temporarily, a glimpse) can actually boost the ego upon re-integration. There is stuff written about it, IIRC they call it an inflated ego or enlightened ego which sounds like a paradox. It is, it's a lie, and it's not really uncommon.
As I understand it it's partially confusion, your ego thinks that it itself is getting enlightened which is nonsense because it has to shut the hell up to go in that direction. And its partially a defense mechanism perhaps, since the ego is programmed since quite young age generally to fight for its right to exist and transcend above other things and prosper, to get ahead.
You see it in the new age scene as well, people get a small glimpse of mystical or enlightened states... some then feel like they're onto something (can be confusing and/or constructive), some go much too fast and actually become more self-centered. I've been attracted to it as well and tried to stay out of the pitfalls when I noticed this. That is not to say I feel above it now but realizing you are kidding yourself thinking you have just become an enlightened being just like that is the first step on the path to getting over yourself, which is a good plan.

I am not involving myself in enlightenment that much anymore, I believe in meditation and mysticism in the sense that we sometimes need to just let go of all the endless rationalizing, trying to understand and conceptualize. It doesn't really promote a feeling of peace and balance.
For the record I think that mystical states and enlightenment are extremely often confused with each other, that mystical states are much easier to induce and take less work than (temporary) enlightenment and that the meaning of enlightenment is that reality awakes from the dream that is you and NOT that it is you who awakenes from the dream that is reality.
Sorry if it seems like I went totally off-topic but my main point is that tripping can make you deluded in the falsely awakened ego kind of way I described and that can be a reason why people think they got the answers, that how they see things is objective all of a sudden. Either that or those people were like that before they ever tripped and they just didnt go full-monty in those trips. A real shredding deep trip can be quite humbling and has a bigger chance of stripping away leftover pretention. At least for a little while
