Nature or fantasy.

I need to find something else to photograph when I go out and do more photography, I always seem to photo nature and things that aren't man made and if not plants then objects that are outside but I think I need to find some more interesting things. I want to do some fantasy themed photography but I'm really nervous about going out and looking like an idiot when I do it. I've got loads of ideas written down but sometimes I just want to go out with friends. Although they all say they will come out and do some photography but it's always the same person that will actually do it and the others seem to get put off by this person. Eugh. I need help:(
