First of all, I don't think people have all of these at once- people tend to be primarily visual, or tactile, etc, so they will have more of a tendency to have one type of phenomenon over the other.
If someone is having visions at a bad time or hearing voices when they don't want to, they might have natural clairsenses, but they also could be developing some sort of mental illness, especially if the activity started out all of a sudden.
Any time that I have had unwanted experiences, usually asking my Higher Self to help stop them has worked for me, and a lot of grounding and immersing myself in physically based activities have also helped.
