I try to look for commonalities in dreams to look for patterns and things maybe my subconsiouse is trying to tell me. It seems your dreams all involve warning people and the other end not responding, or knowing something important that know one else knows. You also seem to have plans devised in all dreams for escape...The rest I think is like parper doll says is personal and maybe only relates to you and hatherefor hard for other people to read into.
If I were to have those dreams I would make a guess that people around me dont value my opinions or ideas. The element of paranoia would make me think I'm also unsure of myself and my actions and direction in a given life situation.
