He thinks he is being watched by everyone

 all the time. he thinks i see what he does even though i am not looking.

he watches all things people animals places constantly

keeps blinds closed at night. took yrs before he believed me that no one van see thru his bedroom window blinds or living room and kitchen blinds. he had to go outside at night when lights were on inside and see if he could see my shadow when i was inside house several times before he believed it

he has thought people and police were following him. he warns me to check all the time when i am driving to be sure no one is following me .

paranoid.
