For most of my life I couldn't tell and didn't even know that I was doing it. However, these days I get a feeling of detachment like I am going "back of the bus" and becoming a watcher not a doer. I get dizzy, light headed and feel like I am falling asleep or like I am drunk which bites cause I hate the drunk feeling.
At this point I try to do something that shocks my body systems like a cold shower, drinking ice cold drinks, I have also found that when my husband and I have intimate relations that forces me into the present as well and helps me maintain control.
Hope this helps
