One of the last times I was on 300 mg dxm, I was going to drive, but as I approached the car I got a strong sense of foreboding and turned around as I realized I was too intoxicated to drive, it felt like something kept me from it. I looked near the stairs to my apartment building and there were three people, more like silhouettes but not really black just couldn't make out their details standing there talking, felt/looked like three males, this was at night. Then I turned away and turned back and they were gone and I was convinced they were guardian angels. Granted I was high and may have been hallucinating a bit from the dxm as it's known to produce psychosis, but some claim it brings you closer to the spirit world, but that can be dangerous if you don't know what you're doing as I am quite ignorant still in supernatural matters.
Also admittedly I take this with a grain of salt as I feel it arrogant to presume I'd have guardians of some sort (maybe they were guardian demons, I don't know) while innocent children starve to death every day and so on.
