First time having a blackout – I apparently called people “gay” while drunk.

A few weeks ago, I drank way too much alcohol without realizing it. I was conscious at 1:30am and woke up after everyone left (around 7am). I vomited and slept through the entire night. According to a friend, I was calling people gay. I never had any homophobic thoughts and this honestly surprises me. Is this normal?

I feel like what happened was really dangerous since I was left alone around hundreds of strangers in a vulnerable state. None of my friends called me an Uber or gave me water.
