I had a dream last night that a "mini-penis" grew out of my knee. it was full functioning and I was embarressed by it. I called a doctor who came to my work (coffeeshop) to amputate it. insight?
It probably means that you will soon have a sexual picadillo, say a fetish, or perversion. You will then realise the futility of it all and will decide to turn your back on it, refuse to think of it, refuse to entertain fantasies of it.
I think white feather is right, just a little too specific. It might mean that you will develop some sort of trait, or an attitude that you only take up for a short period of time... and then something will make you immediately abhor it afterward.
