If you can trust your pdoc or T, then yes, it could be helpful. To me, they are all on the same team of conspirators who want to lock me in the clink. The ones I've seen don't care about the details. They want you out of the consulting room as soon as possible so they can improve their turnover. I'll tell them as much as I deem necessary to get the help I need.

I agree with Yagalada that some of the more ethereal or strange experiences we have can be useful to us, and need not be medicated away.
