My worst dream 1

On the next three post I want to talk about the worst dreams that I have ever had:

In the first dream I'm on my bunk bed and my bedroom is like a swimming pool .Then when I try to get up I can't move and I see that the water is rising and a white big shark is trying to arrive at my bed and when the shark arrives and tries to bite my body I wake up.

I dreamt that when I was 10 years old and I think that I know the reason, that night I saw a film where a shark was trying to eat some people that were in a ship. After that night I sometimes dream something like that and sometimes when I'm in the water I feel that a shark is following me.
