-The general public doesn't take it too well if you talk about anything related to psychic abilities or experiences.
-Mainstream science is not quite at the point of accepting the validity of scientific studies performed in parapsychology and consciousness research, i.e. there IS proof of psychic functioning (telepathy, remote viewing, clairvoyance, precognition, healing, psychic diagnosis, psychokinesis) however most people remain unaware of these results, and many others maintain a pseudo skeptic outlook (whereas real skeptics would investigate the available data, pseudo skeptics don't bother).
-The effects of psychic abilities are poorly understood. You might harm yourself accidentally by overdoing it. However, this is for you to figure out.
