i believe that i have experienced it on enough occasions with enough consistancy in experience to say its subspace. i lose complete track of time, my sensations get mixed up...like a drop of sweat may feel very hot when it hits my skin, i become incoherent yet i think i am using words, i sometimes tremble all over. as i come out of it i usually become conscious of being very cold and need to be wrapped up and as i get a strong feeling of vulnerabilty for which i have name ppv (post play vulnerabilty) sometimes that lasts for quite a while. as for what brings it on, that varies...sometimes i go there quite easily and other times it takes a fairly intense session. Pain isn't always the thing that brings me there either. Master has His own tricks for that He would have to explain as i am usually surprised that so much time has passed. i had never done any reading on the subject and didn't know what it was when it happened and Master was kind enough to explain it to me, but it wasn't scary at all. the only note is that i can't be trusted to use safewords and he has to keep an eye on me especially with any bindings as i can't always tell when things aren't right when in subspace
