Terrible sleep

Has any1 had intrusive thoughts about sleeping and why we sleep? I love sleeping and taking naps but I get thoughts like your going to forget how to sleep and I'm like what? That makes no sense

I have barely slept in three days, maybe two hours a night. I feel so overwhelmed and uncomfortable right now. I cannot, for the life of me, stop confessing. I feel absolutely unforgivable, like no matter what it is, I am irredeemable. These waves of guilt and dread keep hitting me so hard. Every time I sleep, all I do is dream-ruminate. I analyze every tiny detail of whatever I am obsessing over, even in my sleep. It almost feels easier to stay awake, not that I have been able to do anything else. I feel so drained. I am scared to sleep. I hate my brain. I feel so anxious.

bruh I was sleeping & I suddenly am woken up by one of my cats. idk what was happening but she was making a weird howling noise. her tail was puffed up and she was either looking out the window or looking at my other cat. I told her to be quiet bc idk why she was making such a weird noise. thing is, I never heard her do that. then when I threw something on the floor (my bed is a loft), they both kinda flinched. I didn’t hurt them but just needed my girl to relax. they were both looking at each other & my girl was growling/howling at my other cat. idk why. like ik sometimes they fight but she was being weird. anyway, I had to use the bathroom so I did. the door to my room was open which meant they could get out if they wanted. they didn’t. they were by the window. very odd. came back up the bed & now my mind is frightening me. thoughts are racing, ranging from: there’s something/someone at the window, likely some shadow figure to my cats secretly being possessed by some mysterious entity. my mind goes wild & when I’m suddenly woken up, I’m still in that dream state. idk how to put it but my mind starts to believe things and I feel very vulnerable. literally it’s night and everyone else in my household is asleep. these moments felt like nightmare fuel & any sudden noise triggered me. like I felt maybe my cats were going to stand on their legs and chant some shit idk. I wanna go back to sleep soon. I need my paranoid ass to calm down. at some point I started to get kinda freaked out just looking at my cats. ruhrjfjdsnnfnf I hate waking up suddenly at night T_T
