Dangerous? Only as much as you want to swim in nihilism. Someone who claims you have qualia, a soul and a psychic commitment to astrology or whatever is more dangerous because that person has an affirmative commitment to maintaining that belief.

Qualia is generally argued by Sam Harris to be simple or reductionist elements of our human experience we can all agree humans share. Burning your finger on a hot stove and recoiling is a conscious experience every human shares.

The soul includes way more ideas and depends on who you talk to. The word has been overloaded a bunch, but generally can be said to include a higher spiritual aspect.
