Man, I can only find sensory deprivation tanks when I google it xD I guess you mean more in the sense of Spock being deprived of some sense (because of torture, trauma or what have you)? Or do you mean like sendep therapy?
….there could be an interesting story if you combine it with his touch telepathy or what would happen if he (temporarily) lost it for some reason. I read a fic once with interesting conclusions about how he would disassociate ppl because he doesn’t recognize them without the telepathy.
I haven’t fully thought it through, tbh. I just saw a thing about how people use it and it can be good for them, but if you have it for too long, people have issues with sense of time (people will automatically go to a 48 hour wake period if they are left with no sense of time).
I think it could be interesting but I really need to do some research and think about what it would mean to Spock and do to him.
