My own experience where I have summoned and thought nothing had happened was similar to yours, forget the full details, but I called an entity, considered it a fail, banished and tidied up and decided that since that one had failed, I would forget it and try another one within a few days. Some days later, I see an entity, totally unbidden as far as I know and it just won't go away LOL
When I mentioned it to a friend, he pointed out that it sounded very much like the one I had summoned a few days earlier. It was LOL - I had completely forgotten about it.
I think the lesson learned for me was that I need to up my banishing techniques (IMG:
