In general it doesn't seem like memory is affected; the main difficulty is making sense of what you experienced.

This. I spent a solid year reflecting and trying to understand everything that happened during my first LSD experience. The whole thing simply transcends anything you have ever experienced.

When you “see” a strange loop involving your mind creating the physical world as you know it, and at the same time realizing the physical world enables your mind, it can take a long time to unpack. Sure when I’m here, we say that the mind is just a construct within he physical world, that just happens to be modeling the physical world. But that Doesn’t make it any less of a significant experience.

It was like seeing the concept of ying-yang (duality and mutual dependence) reflected onto mind-body problem, and everything else.

Oh great times when you get bored of all the analytical logic problems of the everyday world. :)
