Last night I was raped by something, a ghost? demon? I have no fucking idea.

Last night I was alone. My husband is working nights so after drinking my herbal tea I climbed into bed. I woke up feeling pressure on top of me, I thought it was my husband but nothing was there and according to the alarm clock he had 2 hours before getting in.
I was struggling to breath and was fighting to roll off the bed, but whatever it was, wasn't going to let me go.
I felt claw scrap down my breasts, the pain was unbearable. I tried to scream but nothing came out. I was suddenly flipped over and I felt the claws scrap down my back and arse. My body and will gave up, the pain was too much and I couldn't fight anymore.
Then I felt it. A dagger like object was violently forced into my vagina and whatever it was started to fuck me with it. I could feel blood and other liquids pouring out of my wounds and vagina.

After what seemed hours it finally stopped. I staggered into the bathroom and looked in the mirror. I was battered and bruised, covered in blood and semen. Mu husband then walks in and see's me. I told him what happened and he looked around our house to see if there was any sign of a break in. All windows and doors were locked.

I know this sounds crazy, but it happened. What can I do to stop it from happening again? I'm terrified of going to bed. I saw nothing. I was alone...so what the fuck did this to me?
