Is nihilism known to cause strong reactions in a person introduced to the idea?

I my spiritual seeking I had been coming across various ideas some of which are very nihilistic. Such as that there is no self or you don’t really exist or the world is a dream. When I share these ideas it almost always had a reaction. In one case it almost lead to a physical fight and created an enemy. In another case the person communicated it was evil and I was doing evil things. In another case the person used it against me to paint me as someone possessed with evil spirits and made threats. In a few cases the person became paranoid of me and long afterwards seemed afraid to hear me speak. They always nervously avoid my sentences or anything I try to show them.

I can’t help my curiosity even if it’s to my own detriment. It’s just too fascinating. Is this a known thing?
