I agree that touch in therapy can be very healing for trauma and for certain clients. I think it might be really good for you providing the boundaries are made very clear for both of you. I feel strongly that she needs to be clear about what she's doing, why she's doing it and how it's going to help, it would be very unfair if it was handled badly and it threw you back to a very disorganised place.

I would take time to think very carefully about this Rainbow, what you hope to get from it, how you feel it will help, what will you do if you really can't handle it etc How she will handle it if she decided it's not helping but hindering you...
