Are people able to see ghosts?

I have a dilemma, I admit, and it is about what in the "world of mystery" is known as mediumship more specifically, the sensitivity to everything that has to do with the paranormal. In all these years dedicated to this subject, it was dismantled and felt well. As a general rule, they are usually charlatans with the sole desire to be noticed.

Now, there are other cases that have really left me "with two palms of noses". People who go to a place and are able to feel all that bad has already happened. It sounds like a movie, and in fact, it's normal to mistrust and think that it's crazy to come to believe in all of this. Now do we know everything in this world that does not surround? I think in this case the answer is obvious. Every day new discoveries are made on a scientific level, findings that a few years ago, in the most similar to the most preposterous.

It may be that people who claim to have this gift have something in their brain that today can not be explained by science, remember that we only know 20% of the potential of this part of our human body. I think it's all the time that we open our minds to the facts that, no matter how far-fetched they may seem, may be real. In fact, this is how science advances, right?
