Is apparition the word? I don't really know what it means, so if I saw one, or do you have one, I wouldn't know. Here is my version of an apparition, a tall veiled woman suspended in a tree. Beats a religious shape in a slice of toast hands down.
Actually, it is a towel that has blown off someone's balcony and ended up in the tree. Assuming it is from this building, you are not allowed to dry washing on the balcony, so it serves you right that it blew away.
However, charitable soul that I am, I am just letting you know what happened to your missing towel. Just in front of the bank. Get a long stick or something to retrieve it.
