I don't think your feelings about this are weird at all. I completely understand and feel the same way. I always "need to know". I do not like surprises and stuff like this throws me off. I need warnings due to unpredictability rooted in the past. However, once I did get the courage to speak up about his background visual that really effected my comfort level during online sessions. It was a very large, aggressive, bright, disturbing Chinese circus poster of a wild beast gnashing his teeth....really off-putting and jarring. Who wants to look at that staring back at you while trying to feel safe and secure. It was a huge picture that took up a large part of the screen and was a huge distraction. Well, he was pissed and 'scolded' me for being ridiculous, trying to shame me for being effected by a picture. Just one of many memories coming back to me and confirming this ex-therapist was a horrible person and a pathetic excuse for a therapist.
