Insomnia rant plz give suggestions

I was trying to sleep in an aunt house and I’m suffering from nightmares or when I take naps or sleep I dream horrible things, and I took a little nap and I was about to start having a nightmare and I woke up. There’s a person that lives here and he’s not even here but I was about to have a dream with him it’s so scary he’s not even my family member or anything. And like it’s a delicate topic. But it’s the feeling that I can’t even sleep sometimes without dreaming this things that are so scary . And the groinal responses are about to kill me ! This is truly destroying my life I don’t know what to do I don’t want to be like this but I’m too tired to stay awake and too tired to sleep

I have, alongside my other OCD themes, an intense fear of insomnia. Although this has been improving somewhat — partly thanks to medication and The sleep school on YouTube — I still find myself ruminating about it throughout the day when I have something important the next day, I get stuck in the fear that everything will be ruined — for both myself and others — because my mind is so preoccupied with sleep. + a fear of depression coming back. It honestly feels like a form of sleep OCD. I'm not sure if that’s an official thing, but that’s how it feels to me. A form of erp is the idea of befriending wakefulness. That works great tbh. Things like sleep hygiene, meditation, etc. — tend to backfire because my OCD latches onto them and becomes too obsessive about “doing them right.” I’m genuinely wondering whether ERP — for example in the form of a worst-case-scenario audio loop (imaginal exposure) — could be helpful in this case. I’m hesitant to start unless I know it can actually help. Is there anyone who has experience with this or thoughts about it? I’m not looking for reassurance or tips to fall asleep — only for ideas on how ERP might be applied in this situation.

I feel like it’s just me. But at night when I start to fall asleep, play on my phone, or watch TV; I’ll get major intrusive thoughts and a butt load of anxiety. Has anyone felt the same about this? How have you managed it? It’s getting exhausting and even causes me to sleep-less.
