Anyone ever get angry post-therapist vacation?? I just am feeling a surge of anger toward him. I met with him yesterday and was very detached, but didn't have any negative feelings, really. But I was acting kind of like a teenager - noticed myself smirking at him here and there

I went home feeling very detached and like I don't need therapy anymore - I'm fine now. I did notice a huge reduction in the anxiety/depression related to my past. I was doing better, although not feeling much of anything was a bit concerning.
I then had several dreams about him last night which is very out of the ordinary. The one I remember best, I basically told him over the phone that he doesn't care about people and I'm really not looking for a therapist who doesn't have care for others. I was like, "look T, I don't need that. I'm looking for someone who cares." The other dreams he was acting more like a peer and I was talking to him in a casual environment with other people. I was telling him about the same life stuff (practical things) and he was telling me what he REALLY thought. It was refreshing to have him be there like a normal person and not all therapist-y.
So this afternoon, a surge of anger came over me. I am feeling agitated and hardened. I am trying to figure out why as nothing happened, but I feel it toward my T. I'm mad at him and I don't really know why. I do think him going on vacation triggered it because he didn't do anything different last night. But him being off the past week is so not a big deal! So why would it be contributing to these feelings? I mean, everyone needs time off and I want my T to take care of himself. But when I think of him, I feel that anger thing in my chest, I feel pissed off! That's so weird....not sure how to approach this...or if I even want to tell my T. I do NOT want to be high maintenance.
How typical of a response is this? I mean, he gave me notice and prepared me for it. Seriously...I feel like need to get a grip /:
