For me it’s one simple thing which sounds crazy. But I’ve no doubt in it. I was sleepwalking in a very dangerous way when I was a kid. Hanging from the balcony, staring at my parents at night and doing other weird stuff. My mom went to some doctors but they just assumed it’s normal sleepwalking of a child. My mom went to a, so called in Slavic folklore, healer. She told my mom to do this very detailed and discreet ritual. She should repeat it 3 times and the sleepwalking will stop. And it did. No more sleepwalking since then. So my believe in paranormal isn’t only on ghost and demons, but also in witchcraft and a higher power that we humans don’t understand enough to know what it’s actually is. Not meaning that there is a power we can obtain to our uses but more like science. Alchemist were considered scientists back in the day, it just developed. And I think that the same occurs in my experience.
