Woke up to weird bird chirping and now I'm anxious

This morning I had the realisation I might have fallen asleep on a random stray kitten that snuck into my house, obviously I can’t find it anywhere in my house nor can I find any bodies of a dead hurt kitten anywhere home neither did my family, but each of these scenarios can be explained by either the kitten leaving my house in agony and dying outside or my family just lying about finding one as to not hurt my feeling. How does one go aout such unverifiable thoughts, how can I know I didn’t fell asleep on a kitten when I can’t really feel it on a soft bed when under me? Or that it might have jumped on my bed last second when I’m laying on it after I checked there was nothing on it? I know it’s unlikely but I can’t keep living like that... I spend several hours not sleeping yesterday night vecause I kept checking under me while in bed never being satisfied and sure I haven’t falle asleep on a cat and just forced myself to fall asleep regardless but I feel guilty now...

I’m new to all this and just wanted to post what I’ve been going through. After experiencing hallucinations from sleep deprivation, an overwhelming fear of possibility developing schizophrenia has become like.. a theme for me? I also have visual snow/bad vision so lately, I guess a compulsion I have been doing is double checking if I’m seeing stuff or hearing voices, but it’s nothing. I’m just stressing about a sound of an ac, for example, y’know? Another one is checking my heart constantly in fear of a stroke/heart attack. Any body sensation or muscle twitch makes me spiral so bad. It’s gotten to a point where if I laugh or get up from my bed, or do something that requires physical movement, I stop to check my heart and panic if it’s fast. This all has just been so distressing for me and I have a lot more things that I think and worry about obsessively. It’s the constant what ifs that are so debilitating.

It's been 2 nights in a row that I haven't been able to sleep normally, last night was horrible, I only slept like 4 hours and all night long I kept having bizarre "dreams" and I kept having this kind of mind chatter, where random words, phrases, songs or even images kept popping up in my mind non stop for all the time I was asleep. It got so bad and uncomfortble that I jolted up in a panic and couldn't go back to sleep I was so scared bc as soon as I closed my eyes seconds later I would start getting those random sounds and images in my sleep and it really frightened me. Is this normal or anyone has this? what worries me is that it lasted the whole time I was sleeping, not just for a few minutes.
