been thinking on your question, shock, it depends on what type, it can seem a withdrawl the world moving around in a strange almost sickly way, sometimes pivoting, possibly interjected with sudden what seem like fast time clips from the world around, numbing softness, or can go the other way, not responding sitting there, just not noticing the world around, the world around isnt there any more just shut down. takes different people slightly differently, but theres definitely the common factor of being somewhere else, sometimes something physical as a give away such as behavior , repeating something over and over or, just not responding. does it seem fresh? yes at times a second away sometimes thinking about can bring it back, does dealing with it in a therapy setting in early onset stages help, possibly in dealing with coming to grips with the initial thoughts to stop them going 'deep' try and stop them hiding, dam brains fragged thinking about it, but yes. there are differen stages and intensities varying over time experience and how you deal with the things causing the problems, sometimes compounded by further avoidance and non recognition of the problem, what would advice on the scene be, how to deal with things what not to do, avoid drinking, look for signs of avoidance hyper vigilance withdrawl etc and come up with a frame work to help the individual also the problem of dealing with recognition of a problem by the individual so when dealing with on the scene also try to think about relatives or partners of someone effected and how they can help and recognise signs of problems. did any of that make sense in what you asked?
