Most certainly! I have wild dreams myself. Just last night even. In fact it is so abstract I can hardly describe it. Keep in mind our dreams are our mind's way of working through unconscious preoccupations, as well as simply process the onslaught of information we receive each day. Perhaps, look inward a little. Evaluate your inventory and concerns a little. Aside from that, I wouldn't read too much into it. The human mind is a fascinating thing!
