The first time I took LSD it unlocked a level of thinking that I was not capable of before. For example, other people's perspectives. I fell down such a deep rabbit hole of contemplating other people's feelings and perspectives that I could literally (in that moment) FEEL other people's feelings. Obviously that is the drugs talking, and it didn't really happen like that. But in the same way that I really did see the wood grain in my coffee table bubbling like a witches cauldron, I also really did have a deep, meaningful, impactful thinking session about other people's perspective.
So when you "come down" you kind of get to keep that fullness of appreciation. The need to now consider other people is there, and your brain is fully aware how important it is now. The experience of appreciating things deeply stays with you somehow.
