I'll have to test this sometime, since (I think) I can be not-suggestible when I know it's coming.
So you think you can reliably avoid to think of a pink elephant?
More importantly, if you want to use "ASMR" for practical purpose I would recommend to maximize the power of the suggestions. Feelings that you create through suggestions are real.

I can't, but I can reliably avoid thinking of any other thing that is presented in the form "Don't think of X" - I've trained myself to actively think of pink elephants in such scenarios (thus leaving no scope for thoughts of 'X'). It works rather effectively. I haven't tested it on extreme cases like "Don't think of boobs" though. That might be too strong to counter.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
