I wasn't well enough when I had the tactile to even try to control them but for the others I find that anything that fully engages your mind will turn them off....one thing I wonder is if the pathway of input must match the hallucination...like auditory responds to sounds like music and visual responds to a change in visual events...so I wonder if you do something that is very touch heavy like playing an instrument or even finger painting or something else tactile if it would block them. I had a certain subset of toys etc I used for tactile stimulation like silly putty an ammonite fossil that was polished etc I have no idea why I needed to feel things when I was getting better but I saw it as relearning things I did as a child to correct/rewrite the neural pathways. Anyway you could try tactile stimulation of various sorts and let us know if it works...
