I guess it depends on what we're thinking? I do this too. I used to do it regarding a previous t to escape into romantic daydreams - i dont do that with my current t. There is some escapism, but not so single-minded or goal-oriented, shall we say? Now it's more as you say, they ARE a part of our life, and i am trying to form a positive introject to replace my mother's negativity, so keeping a positive picture of them in mind may seem childish, but i would prefer to say regressed, as part of a plan for future better mental health.
