Actually, I can imagine stuff. Like, I can close my eyes and see a tree. It's really just combination or imagination. I cannot visualise anything I have not seen yet basically.
And thanks

Ah! not quite the same thing then, though sounds related in terms of some of the impact. I can't visualise anything I
have seen before, never mind what comes from the imagination! Not the simplest object or the face of the person I know best (etc). I can't even recall memories of events and things I've seen, heard, smelt... (blah blah and so on) even a few seconds ago. I only know I know something when I experience it for real again.
Regardless, it has nothing at all to do with how bright you are - don't put yerself down, most of us who seem to lack something often have something else to make up for it!
I, for example, have the superpower of being able to make even the nicest and most tolerant reader here go green with nausea on reading my posts! Weaponised BS! Quake in fear yea peon's!
[Addendum:]
It was discovering this in myself that lead to teaching myself a lot more about brains and minds and perception and lots of related topics, and discovering just
how diverse human perception and cognition actually is. Just how profoundly and fundamentally different some minds can be. Operates on the normal bell-shaped distribution curve whereby most of us are within the standard deviation of how they operate mentally, but a small yet significant percentage deviate from that to some degree, to the point where we have people who perceive sounds as colours and other equally unfathomable (to me at least) concepts.
Despite being one of those wankers who live outside the standard deviation (I'm a
non-standard deviant!

) of social norms, for 60 years I never even considered that most everyone else's mind was working in a
very different way, to the point where english is spoken, english is heard, english is converted into semantics, semantics says ..., um..., er... "My hovercraft is full of eels"!!!! (that last bit's from Python, if that doesn't make sense, that's the idea!


).
In other words the sounds (words) being made were not foreign or meaningless, but the meaning of the whole sentence was irrational or ambiguous at best, often from both directions in a conversation.
The more I buried into this narrow rabbit hole, struggling to widen it enough to fit through (metaphorically speaking) the more I learnt about perceptions and how they work, or at least specific areas in how they work, and ultimately learned much more about how divorced we are from reality in a very objective sense to the degree that objective becomes just another subjective.
Bottom line - we are unfit to perceive and understand reality, and for good reason, it doesn't lead to an entity better fitted to survive in an evolutionary capacity. So our brains are focussed not on what's real or what's 'true' or anything like that, it's instead focussed on what's successful. So the irony is that someone can espouse a totally false paradigm to hang their beliefs or policies (etc) on, and despite how much they are based on false premise, that doesn't mean they won't be successful!
Oh, remember my comment above on 'super powers'? And my weaponising BS? Please now see the example above!

Apologies for drifting off topic just a teeny weeny bit? (though getting stoned and the question of perceptions isn't really
totally off-topic!

)
