A fun aside here: experiments in which people who’ve taken hallucinogens are placed in brain scanners reveal activation patterns which look an awful lot like what we see when we put small children in brain scanners, and this somewhat accords with the neurogenesis vs pathway pruning see-saw model of brain development.

I’ll say personally my experiences with psychedelics brought back memories of childhood - how I engaged with the world, how my mind would go off down different paths, the intensity of focus - so, you’re probably not far off here.
