The mind is powerfull tool creating vidid imagination that many can claim as proof and truth. However, science needs to deal with facts and and system of verifications and confirmations. We still do not know everything what is happening in the universe, and deal with unknown phenomena; however, this is not a proof of supranatural events. Catholic countries are regularly engulfed with vision of Virgin Mary and have more sighting of it than any other religion on earth. Medzhugoria in former Yugoslavia is one of the example. Catholic Croats will insist that the sightings in the 1980's were real. I met Bosniak (muslims) and Serbs who disagreed. Spain, Italy, Portugal has more sighting of Virgin Mary than Protestant Saxony, England and Scandinavia. During forcefull catholization of Bohemia in 1648-1742 there was more sighting of Mary than it was during 200 years of Protestantism. Whatever became popular with the minds of the people, there will be always individuals believing that some phenomenas are real.
I have two or three unexplained experiences and I still not will insist that the spirits are real as they could be coincidence or result of imagination. When my biological father passed away, the night it happened, I dreamt to be with him in the car, me driving. Next thing I saw a skeleton with sickle and my father in the dream told me that she came for him. I woke up called home hundreds of miles away to find out that my dad passed the night. I could never explain this, but this does not proof anything that there is afterlife, Grim Reaper, spirits, or out of our dimension some messenger.
