I'd recommend hitting the JREF forums.[0] For best results, approach them with a single thing you can do that others cannot, rather than a list of things. Minor is actually better, as long as it's something with a causal impact that shouldn't be possible in conventional neurology. They'll help you whittle your ability down to a falsifiable claim, and then design a repeatable, properly-blinded protocol to definitively test whether the phenomenon is real, or has a mundane explanation.

As long as you approach it in good faith, with an earnest desire to discover the truth and the willingness to be proven wrong if the facts go that way, I think you will find they are generally intelligent, respectful people; they do this stuff all the time. Remember that skeptics want to see paranormal phenomena validated more than anyone does; the proper skeptical response to an unlikely claim is, "Well, my impulse is to doubt that, since it goes against every experience I've had so far. But it would be really cool if true-- Show me!"

I'd only also ask, just for me, that you make an agreement with yourself that if the experiment returns a mundane result, you won't discard it but will seek medical help. It may indicate a life-threatening condition.
