Does anyone else experience this?

So I did powder MDMA in a gel capsule with a friend the other night. Just hung out at a hotel, smoked weed, put on some music, and rolled. I'm small, around 100lbs, and I took 80mgs of molly. My friend is ~180-200lbs and took 300mgs of molly.

Along with the normal blissful effects, we both reported to eachother some interesting hallucinations afterward. I have researched this since and I have found little information that this type of hallucinations happen to other people.

Face Changes 1. When I looked at his face, or my own in the mirror, it changes. Not drastically, but it's like you are looking at a stranger or perceiving their facial features differently. And it will change before your eyes. It's like seeing yourself and not recognizing who you are. I know people can make weird facial expression while rolling and this wasn't that.

Frozen People 2. It was only me and my friend in this room. At one point I thought that it was a full party, and that there were other partygoers in the room, but they only stood in the corners and did not move. Like shadows. But it wasn't scary. I enjoy their company. The first time I rolled with my friend, I hallucinated a dog in the same manner.

Has anyone else epxerienced similar hallucinations? Is this a common reaction to Molly? I'm just curious. I have only rolled a couple times, and my friend (who has had experience rolling for 15 years) seems to also recognize these hallucinations but doesn't know what to call them.
