I experience psychoses sometimes. They've never gotn worse than hearing things and seeing things for me, but some people have extreme symptoms.
I had a friend that ran outside in her underwear and dived into a pile of snow outside of our high school proclaiming that the lord and savior had come to rescue her.
The good thing about being with someone you love, is that they can keep an eye on you and tell you if they think anything is wrong. Or call emergency services if necessary.
Most importantly, be careful.
