I've started to notice it a couple of weeks ago. I seem to be able to know when someone messages me online. I get a strong feeling in the pit of my stomach and often when I get this feeling and log into what account the message is in I find that 90% of the time that message and that person whom has messaged me has.

I'm also able to feel when a family member is coming over. Say if my aunt coming over to ask me questions about a situation that same day in the afternoon she's over. I've heard a YouTube mention this years ago, but I don't remember her saying what this is called.

Does anyone know the name of such ability?

Or, is this a form of our gut instinct?
