Scared of ????????

Hi guys, this may be a little long but please bear with me.......

Dreaming frequently again after my mind having some time off.
But keep having scarey dreams...

A few weeks ago i was dreaming i was being given some kind of test.
I was standing with my sister looking ionto a swiming pool which was murky and hard to see into. In the pool was some illuminated fish and something else that was sinister.
I knew the ideas was to put our feet into the water and eat the illiminated fish with our FEET!!!! without the sinister fish attacking us. My sister did not get the idea and jumped in, i quickly hoisted her back out and the task was complete.
I was then in what appeared to be the changing room. It was really horrible in here. There was nothing to see but there was terrible moaning and people shouting and crying/wailing. The room was empty but i knew there was dismembered bodies here. The noise was getting lounder and i was begining to panic as i could not work out what the test was. I knew something awful was going to happen. The noise was getting louder still.
I hooded figure coaked in black appeared and started to move towards me......i was terrified. I kept trying to think what i was supposed to do......as i came really close i knew when i took its hood down i would be terrified........

The bloody alarm clock went off and woke me and although slightly relieved i was annoyed as i wanted to get it over and done with.

Now last nights dream........
Again a pool of murky water with something sinister in it. I was a pool but had all froth on the top but there was something swiming in the pool and it was dangerous. Somehow i floated above the pool and looked down from high up but i felt like i was boxed in as my back felt like it was against a celing, a bit like an out of body experience only looking down on a pool not on myself........as im looking down this creature shoots up from the pool heading straight up at me. As it rises i see it go straight through a body of a woman. Its jaws are wide open and it looks rather like a chinese dragon and terrifying, but it does not reach me.

This dream with the sinister eel/snake seems to be coming more frequent. I was having one about every month now its starting to be a least once a week.

I did go on to have a second dream last night and i wonder if this is related. It was rather long, but the end part was me being called to the school office to see the head mistress but i was not a student at the school, i just happened to be there. In the room were lots of teachers. I knew i was going to get into lots of trouble for telling tales, but i hadnt been. I was scared and was telling myslef i will not cry. i did not cry but really wanted too. I was feeling really intimidated too, these people wanted me to break down but there was no way i was going to.
I kept asking them all what were they doing there and they were saying you will find out.
I said to them but some of you i dont even know, what could you possilby say about me. They were all there to tell on me about something.
A coloured guy was sitting next to me so i asked him well what are you going to say, i dont know you. He said no but he knew my dad and my dad used to beat his mum so he was here to tell them that.
So i asked them so right your all here to some up with one small part of my past to tell on me. They nodded and smiled.

As you may or may not know i had a traumatic childhood some of which i dont even remember.
I wonder if all this is related to that.
I saw a medium recently and she said that i have spent my life running away from myself and i wondered it that was what my dream was saying that i have to face my fears.
Or i was wondering if the parts of my childhood i dont remember are on the verge or surfacing.........if so i hope not i really dont want to know.

Sorry for the long post but this is really starting to bother me and i would really like so pointers to
A what it means.
B how do i reduce them.

I used to have nightmares years ago and they al
