Probably very mild, as I’ve done shrooms once, and I think I told that story before, but anyway :

One night in the old shared house I was staying at, having the apéro with a couple of flatmates, I was drinking from a beer can, and the meager 6 or 7 dried shriveled up shrooms I had had earlier started to take effect. It seems to have exacerbated a specific anxiety I was having, about accidentally swallowing some insect from a opened can. I looked at the can in my hand and sure enough some absurd chimaera between a winged insect (think butterfly) and a field mouse, was standing on the top, plunging a long-ass trunk (think hummingbird moth) into my beverage. I feel like I looked at that thing in disbelief for a couple seconds, then looked away and again at my can and it was gone. I still emptied the can in the grass
