How to sleep?

Like what the hell, I slept at 12:49am today and I usually sleep around 5-6 am get a few hour of sleep and wake up. I literally don't sleep at night. I tried today but I slept 2 hours and I know this cause I have sleep timer set to 2 hours for music. While sleeping I had a dream, is was like zombie apocalypse type of dream and I had this dream multiple times already but it wasn't complete so parts were missing and istg I wanna sleep but I can't, not at night


I have my guard up at night to much. And I feel like I would be able to sleep if someone was beside me but I hate sleeping with people in this house
