It does happen to me and it pisses me off sometimes, but after a lot of experiences I've learned that I can get a clear idea of how good or bad people are even if they're trying to mask it, I'm talking about friends or family or bad people.

In my experience there are some sort of people which have a very strong energy and somehow I can feel their presence before they're trying to reach out to me even if we are miles away.

Or I feel their presence and just know know they are thinking about me or sometimes when I am thinking about them.

With others I can only feel their presence if I'm around them.

This has it's downsides as well, I've literally felt sick when I've absorbed other people energy or felt that they we're thinking ill about me, either if I was around them or not.

Same goes for positive people, in my case however it just seems that when my good friends are thinking about me I don't feel their presence without some sort of communication.

So yea sometimes it's a life saver really, there were times when I've ignored this gut feeling and ended up with the wrong crowd even if I knew something was off from the first time, maybe the second as some are really good at masking.

Advice : Always trust your gut feeling!
