I'm always feeling the need to tuck the duvet under my feet and keep my arms in so the monsters can attack me.
It sounds interesting, what do the monsters look like?
The ones with sharp teeth and ravenous eyes
You do know monsters aren't real? It's a bit weird for an adult to be hiding under the blankets from monsters. You might need some mental help.
No one likes a somatic... look I'm normal.
I know you believe what you think is normal but simply its not. Having any thoughts of monsters attacking you could be symptoms of schizophrenia. I recommend seeking medical help to get this diagnosis.
