I know 2 stories of people with schizophrenia in my life and they share about the same experiences. 

The first person used to be kicked out of the house for the entire night when he was a kid, as a punishment, and it was in a small village in the woods so it was very scary outside. He didn't have any relatives with schizophrenia so it could be caused by unsafety and the sounds of the night and stuff. 

The second person lived in the city and his mom would kick him out as well during the night, and he walked through the streets at like 2 am to the other side of the town, where was a big super market with lights on where he could sleep. The city is dangerous at night obviously especially for a kid. 

I wanted to see if there's any pattern here
