I have feelings of being at a carnival. I think it is because when you are little your mind is blown away at all the variety and cool things to do at a zoo or a carnival. So when your on salvia it is bringing all those memories back. Or your mind is just trying to relate to what is happening.
Salvia brings various realms together i.e. animals, shapes, god, and others. These are healthy visions and you should embrace the fact that you remember your experience. Most pioneers never get to remember their journey. Keep exploring all exsistence.
