Has anyone else every had hallucinations of things not there?

So I went clubbing in Berlin for the first time last night and had a fair amount of k and m and I’m not sure which drug may of produced it or just a combination of the two but I was having various crazy hallucinations of things that wernt there.

For example I swore the wall of the bathroom stall was getting washed away and I could see a clear reflection of a tree in it, I then saw a fly flying around the room and landing only for it to be a screw in the wall of the bathroom stall, then the weirdest ones were near the end of the night when the I was looking at the dj with sunglasses on he appeared to have a ghostly faceless grey face like one of those guys from lord of the rings on horses, only for me to remove the glasses and his face go back to normal. The oddest one was when I was dancing and a guy literally just spawned in front of me and started dancing.

With all my experience on lsd and shrooms I’ve never hallucinated things like that that wernt actually there or happening. It was ducking cool though and I’ve never heard of anyone else experiencing this. Is this from the drugs being mixed as I know m is classed as a psych. Let me know if this has happened to you any of guys I’m curious.

Cheers
