This was literal everyone. Lol. Squirrels really in my attic. My monster cats under my bed and a song that I'd heard earlier that was drifting through my brains. But thanks for the advice

talk to your GP. a qualified medical professional will offer far better advice then an internet forum.

I used to call those brain worms or roof chatter.

It's no magic wand but consider reading a little about Mindfulness. Mindfulness in plain English by Henepola Gunaratana, and The Miracle of Mindfulness by Thich Nhat Hanh are really good and not tough reads.

I had two Hypnotherapists in my family and on the subject of quieting the roof chatter one used to say, "Your mind is like a drunken monkey." A little practice and keep the monkey out of the liquor cabinet and it will quiet down a lot.

I use the mantra Sleep, over and over to get my head to turn off and sleep. Just say it in my head. Only focus on the one word.
