Ugg. I’ve been dreading going

Ugg. I’ve been dreading going to bed at night lately, ever since I had a nightmare a few days ago.
Twice, that night and the other night, I’ve woken up and been terrified of aliens coming and doing weird things to me (I don’t know where this came from, aliens weren’t in my nightmare and I haven’t read or watched anything abou them). So I slept half the night with my light on those nights and didn’t sleep very well since if you have too much light in your room, you don’t sleep properly.
My biggest fear is aliens. Not men in black type or human types, but ugly semi-looking human things that do medical experiments on you.
I’m hoping I sleep through the night, but that doesn’t happen often due to my bladder/kidney problem.
