Im not sure what my new type of psychiatric therapy is called?

my psychiatrist is starting me on a new type of therapy because i have trouble talking about my emotions. she says it will be very fast and possibly resolve my feelings in one session. I hold a vibrator in each hand and they take turns vibrating, which causes both sides of my brain to work somehow causing the frontal lobe to work and it will overall bring up all of the memories and things i have never been able to talk about, but in a way that i am able to think about them with out the emotion. she described it as sort of an out of body experience. thats what i got from what she told me about the therapy. does anyone know what shes talking about or how it works??
