This is absolutely fascinating. Not too long ago I thought that everyone experienced level 3, and occasionally level 4 effects, but I learned that my friends did not. The first link says that it's rare without psychedelic drugs. I've never tried any psychedelics, but I regularly experience level 3 effects, and occasionally level 4 ones too. I can't remember a time when I didn't. I also frequently experience/remember hypnagogia (https://en.m.wikipedia.org/wiki/Hypnagogia https://en.m.wikipedia.org/wiki/Hypnagogia), which I previously did not know the name of. I absolutely love experiencing it, as it's often euphoric, although it can sometimes be terrifying and stressful.
