No, these were just for pictures, but i have a buddy here on steemit @freeinthought who did an experiment of ingesting amanita, and he did not report any light at the end of a tunnel:)

Never tried it myself but read a lot of weird experiences. Yeah sometimes if you go too deep into the rabbit hole it might be hard to find some light.

Nobody knows how deep does a rabbit hole goes and what you might find in there.
