3 am wake up call

I had a weird dream last night. It woke me up. No big deal. Went to pee. Tried to go back to sleep

Feel asleep peacefully......nope, laid there for almost an hour

 Sadly, everything was going through my mind. Not good things. I hate when at 3 am, I am wide awake and I start to worry about things. .

Money

Friends

Family

My cat

Everything

Anyone else ever have this happen to them? Any advice?
