Effects from tiny dose of shrooms while tripping hard on acid?

[joe456]

About 11 hours after consuming about 500 mics and some weed throughout the trip , I consumed 1 small mushroom (quite inexperienced with mushrooms) and also some 30mg of codeine, i then felt the visuals increase, including seeing part of a wall slightly enlarging (not a usual type of visual for me). I took another codeine about 20 mins later and felt the buzz but no further increase in visuals. After eating another small mushroom about half an hour after the 1st one i felt sensations in my hands that I would never usually get from acid, weed and codeine combined. I also looked at the ceiling, hoping it would have boosted my acid visuals to where they were at the peak, i was disappointed, but then noticed an open cupboard door was morphing and enlarging in a way I have never seen from acid. I also felt my heart beat harder and my face was flushed. I meditated for 5 minutes about 12 hours into the trip and it felt a lot different to when I did so on the come-up and peak of the acid. My housemate is convinced its impossible to feel shrooms bellow the "threshold dose" but I'm pretty convinced it wasn't placebo, especially since I didn't not smoke any weed for a while before the shrooms, or while coming up from them. Also I was expecting it to just slightly boost the acid rather than change the trip in the way it did. It also seems logical to me that since acid and mushrooms are both "pushing in the same direction" and (correct me if I'm wrong) work in a pretty similar way, the threshold dose of shrooms should be mush lower while already tripping hard on acid. What do you think bluelighters?
