As far as dreams go, I tend to refer back to Joseph a lot as he interpreted many that had significant meanings that wouldn't only affect him, but many. Joseph translated the meanings, but it didn't mean the meaning would be awesome, but Joseph used the scary meanings like of famine for good when he had that control in a situation. They stored food, they were prepared - all because they listened to those dreams and their interpretation.
I do believe that many believers will receive prophetic dreams from time to time. I still ponder the meaning of some of the ones I have had and still do think about them. They can be distracting at times because you feel in your heart, "That must have some type of significance."
I had this weird dream tonight about my husband's friend when I was napping. He had been wondering how she has been doing for a long time, she has been through a lot, but they were friends long before I was ever married to my husband. I had a dream I came across her and she was referring to someone she knew by one letter and I said, "I'm sorry, if you have told me who that is before, but after all this time away, illness, and such - I have forgotten." and she looked around the room and sad like the person had passed away, but at the same time, she talked about them like they were alive and were talking with them the other day. Either way, there was something very wrong going on with the person she referred to by that one letter and she wouldn't tell me. My husband said there's a few people she has referred to by that same letter, but we can't be 100% sure. Bothersome >_<
Other dreams I've had seem to regard more apocalyptic type themes, which are quite frightening at times.
I don't see anything wrong with sharing dreams unless we're specifically told by God not to or something. We all have dreams, people are interested with dreams.
If you've acted out on it without knowing the full meaning in such a way, just ask yourself if it was the correct thing to do or not. It's okay if we say, "I don't know what that means," because sometimes we don't. Pharaoh didn't and that's why he needed Joseph, who had that gift to translate them. Perhaps before acting on anything, ask, "Is this what God would want me to do?" and pray about it to God.
