Pardon me if this has been discussed at length, but I briefly searched and couldn't find anything significant.
A psychedelic experience is very difficult to explain to someone that hasn't had one. We can talk about things that are different and how they relate to the five senses, often visually, but really it's a shift in reality that I don't think anyone could ever go in and come out of it saying, "Yep, that's exactly how I expected it would go," just from having someone describe it to you.
So I'm wondering if there's any novel out there that has done this well. It'd actually also be even better to have suggestions from people that may not have had any personal experience with psychedelics but have found someone else's writing involving this area to be great. It's unlikely one would have an audience that have all undergone an experience such as this so I think that that perspective would be important, too.
Also, just to make it clear, I'm not advocating the use of illicit substances at all.
But to be even more clear, I'm really looking for authors that have written about characters that have experienced ego death.
