I only slept 2 hours last night

You ever have days when you just can't sleep? And idk why there's nothing really on my mind at the moment or any other reason why i shouldn't have slept. I had a camera alert this morning and there were 2 pitbulls in my driveway and it gave me a little axiety because i kept thinking what if they were aggressive and i or my children went out there not knowing that they were there.
