Well, most of us here (I would think) have many experiences: if you never got round to reading my dragon tales, then they are proof if you like of my experiences with my companion entity:http://www.sacred-magick.org/index.php?showtopic=574
I have other things but since I may want to work with the same entities again, I would prefer not to disclose the rest.
I will say though that I recently summoned a couple of entities to help with a project I was working on (now abandoned) and banished as usual; didn't think much about them since I did not get to see them, although I did appear to get some benefit from them. Problem was, another member of my family saw one of them too and was not amused at all. I suppose someone else seeing them is proof in this case. The other proof came in the form of things happening due to that summoning that I hadn't planned, all good fun, well after the whole mess is sorted out and you finally get to banish them
