Woman fears being watched by ghosts of her loved ones

I am in my 40s and have never lost anyone close to me. Unfortunately, my darling mother-in-law has terminal cancer. I am now preoccupied that people’s spirits are near us after they die.

Please don’t laugh, but it gives me the creeps. I don’t want to think my mother-in-law will watch me making love with my husband, that my father will watch me in the bathroom, or that my mother will be critical of my spending more time with my kids than cleaning the house as she did.

Am I crazy to think I might not have any privacy after my loved ones die?
