Strange feeling

Sometimes I wake up in the middle of the night and feel that someone is breaking in to my apartment. Since I don’t sleep with my glasses on I can easily imagine someone standind in a shadow behind a bookshelf or even better my imagination can change to bookshelf itself into someone very dangerous.

I lie nude on my bed and begin to think what to do. Should I just pretend to be a sleep (and let the burglar steel all my properties), should I make a noise or a small movement so the burglar will be afraid and run away (or will he be afraid at all), should I attack him right away or get on some clothes before the attack [thank you Stina] (will he maybe kill me)?

Usually before I do anything at all I realize that there is no one to attack [thank you Stina] or to attack [thank you Stina] me. My eyes begin to see, I put on my glasses or I wake up. And then I have to go to sleep again.

I hope I’m not going crazy.
