Has anyone been stuck repeating jumbled sentences before?

I split a 6 gram lemon Tek with my girlfriend. The first half of the trip was amazing but the second half was like her turning into a different person. She kept repeating nonsense over and over again for 4 hours. I legit thought she lost her mind. She seemed to have been repeating things she has said throughout the past month. 6 hours into the trip she snapped out of it and didn’t remember the last 4 hours.
