I don't use dream signs, but I do tend to have a lot of dreams where I'm running or sneaking away from something. Sometimes I also have an urgent sense of needing to escape, as if I'm being chased. These dreams aren't usually nightmares or heavy in nature; many of them are action- or adventure-type dreams. It probably only took me two or three entries because the commonality is easy to notice, given most of the dream involves this particular "sign" or content.
