I was diagnosed as bi-polar with schizophrenic tendencies.
During my last "episode" I kinda believed that people could read my thoughts:
I felt like all the electronics at work, phone and electrical lines (worked as the phone operater)
plus the metal support beams and trusses etc amplified the situation.
It was like my mind was so open that it was also open to/on a subconcious level.
Other people were picking up stuff from this subconcious link.
It wasn't until I thought they could get my pin numbers that I sought help.
