The dreamer may be feeling hunted, pursued, or stalked. If a person sees himself being followed in a dream, he is possibly in danger of some kind and should take note of who is following him and the context of the dream.
Some believe that if you are followed in your dream, it represents an overactive personality. Others claim that it signifies a stalker. It is also possible for the interpretation to vary depending on who is pursuing you so it’s important to think about who is following you and what their motives could be.
The feeling of being pursued or stalked can also cause stress in real life which can lead to insomnia or other sleep disorders.
