I suppose this is why the mind palace of memory is difficult for me to utilize.

I have read that eskimos lost in the snow and ice have been able to have day hallucinations visually as well auditory. They see and hear birds which do not exist.

A YouTuber simulated it with thick white paper taped to his head with white noise playing head phones after 15-30min, iirc.

Another avenue to look into aside from hallucinogens as referenced in the link could be deep meditation.

My inability to do the mind palace thing is one of those things that suddenly made sense to me.

I've gone deep down a meditation rabbit hole since learning about all of this. No visual imagery yet, but I do see what I would have to describe as a non-specific shimmering/morphing "wave" that comes and goes. Nothing that I could describe as an image of something, but visual phenomena nonetheless.
