This definitely sounds like an anxiety thing. Happens to me often from time to time. What has helped me was establishing a bed time wind down routine. Do you have any routine before bed? Mine is brush teeth, wash face, take melatonin, spray lavender pillow/sheet spray, listen to calm podcast until I drift off to sleep. Establishing a routine before sleep will help your brain refocus from the stress of the day on a task that will put it to rest. Going straight from the day to day immediately to bed without a buffer would almost always have me anxious and restless at night when trying to sleep. Also getting new pillows helped me a lot as well. I hope you find proper rest soon 🙏🏾
