the creepiest paranormal experience I've ever had

On my freshmen, I had the scariest dreams I’ve ever had. When I had the first scary dream, I didn’t think it was paranormal stuff, but when that kind of dreams were frequently, I changed my mind. In that year, I lived with my cousin, so I told her that I had that horrible dreams. She said that She had similar dreams that period of time. I didn’t expect that answer. The dreams were about murder mostly. We put all nighter with this things. We slept very bad so we thought to do whatever to stop it. So I told my mom what was happening. She wasn’t surprise at all. She gave me a bottle with water and told to put it at the kitchen. I thought “ok…I’ll do it”. So I did it and suddenly all the scary dreams disappeared. We were so happy, I don’t how it happened, but it worked, so I didn’t questioned. Now, I don’t have creepy dreams that often, but, that holy water kind of thing, did its job, I don’t know how to explain it.
