This is the definition I use as well.

With that definition, I think transference can explain at least a proportion of our feelings every day, perhaps every hour. Also agree that disliking doesn't necessarily have to involve transference. If I don't like the sound of a nail scratching a chalkboard, that doesn't mean transference is part of my feelings. I just don't like the sound. Same with liking a T or not.

I would find it hard to believe that someone doesn't experience transference with another person. The one-sidedness of the relationship encourages it when it comes to therapy. And the more blank slate the T, the greater the intensity. That's also why psychoanalysts who do therapy can be harmful if they are not fully competent or careful. They give a lot of space, which I find helpful, but sometimes too much space causes the dissolution of boundaries between the therapist and client, resulting in a boundary loss type of psychosis.
