Yes! Yes, this, exactly. I do it a lot.

Furthermore, T has suggested to me that I do this. He said, as near as I can remember "Maybe you could picture me there in the situations when you feel scared and lonely, and know that I am somebody who is completely on your side?" I suggested that that would be kind of intrusive of me, to imagine him there when he might not at all want to be there in some situations, and he suggested that I was talking complete rot, since I wasn't actually going to carry him around physically.
