We INFPs can absorb external negativity into ourselves until it forms a black hole in the center of our chests and destroys us. That's our magical power. Pretty neat, huh?
I've heard that we're all empaths, and some of us can't turn it off at will, so it gets pretty miserable, especially if we are surrounded by negative or hostile people or have to be around too much conflict.
I find myself extra receptive to the thoughts of others when I am sleeping. If someone is in the same room as I am, reading something late at night while I sleep, I will dream about whatever that person is reading about or thinking about. It happens just about every time.
I also occasionally pick up on songs that people have stuck in their heads, but I don't know the source when it happens, so I think that I am thinking of it randomly until I start humming it and get a shocked reaction from someone.
I am an artist, and I find that when I draw things without a plan, just letting the art flow out, the things I draw end up relating to experiences that I will have weeks, months, or years in the future. Usually this is disturbing when it happens because the drawings that come true are rarely about positive things. This ability is just as useless as knowing songs that are stuck in people's heads because I have no way of knowing which drawings will relate to the future and which are just ordinary art until after the events that I draw about happen, and by then it is too late to change anything.
