OH! (((esthersvirtue))) It IS important..and very normal to have this happen! When a T becomes safe to you, then it allows for you to begin to design what "safe" means IRL for you.... usually ppl who have had abuse in any form have had their trust trampled upon..and they no longer have good lines - if any- of who they are, what they are allowed to feel, how far away or close other's "should" be...
T's model what a safe, good relationship should be. We have to work with that, thinking, dreaming, yes sometimes fantasizing, about what we wish... and from that you form new, safe parameters for living.
IMO, it's shows progress in your therapy journey, and is commendable

(PS, you are also correct to not act on the "out of bounds" thoughts... that, too, is part of your relearning safe relationships.)
