Parapsychology and intuition

Hello Rabbi,
In the series of lessons, the Rabbi said that in parapsychology there is one study with strong significance and validity, regarding "the feeling that someone is watching you." I couldn't find it, I would be happy if the Rabbi could point me to a link or source.
 
Another question on another topic, the rabbi said that therapists have referred people with OCD to him to help them. I think there is a possibility (also from my personal experience treating people with OCD, and on myself) to treat mental disorders through philosophy. Although it is not of interest to her, it can be used to dismantle the mental failures that underlie a significant portion of the disorders. Does the rabbi know anything about the subject by any chance?
Also, how did the rabbi help them, if I may ask? In what way?
Thank you very much.
