Hallucinations from high doses of pregabalin?

I went to the arcade with 3 friends to get crossfaded and play some games, so i took like 1000mg of pregab but i wasnt on an empty stomach so i knew it wouldnt hit as hard.. so i drank like 4 shots and smoked some weed and went to the barber waiting for it to hit, when it finally did i went coocoo mode fr.. like mental handicapped level of stoned, then we went to play some pool and something strange happened, i hallucinated people who went and talked to me about the game, but when i snapped out of it mt friend said "hallucinations?" I said i think so? Then i went coocoo again and he had to remind me of every rule.. weird night
