One gal tried to do DBT with me and I found it incredibly boring - all those handouts with long numbered lists and acronyms, OMG! But I do remember grounding exercises - that is all that I remember from all her efforts. You "ground" yourself by getting in touch with the sensations of where you currently find yourself - that would be noticing how your H's skin feels to your palms and the rest of your body, what smells there are in the bedroom, etc. Grounding is supposed to help with dissociation as well.
