People with a soothing presence?

Bit of a weird question I guess but has any one had this kind of expreince when I don't know perhaps there is some one you may know that has a some what soothing effect on you.

For example when the person is around you perhams become more calm or feel quite relaxed and clear headed around them, like they give off some kind of possitive vibe.

Simply curious if any one has had this kind of expreince ?
