In reality: I work at a day care centre with cute little 3 year old kids and other s like me who work there.
My dream: We went on a trip (the kids, s, and I) and we were in this very gloomy town. At the end of the town was a hill with an old old castle on top. On the bottom of the hill ,there's an old gate made out of wood. The other s and I have notified the 3 year old's to not enter that castle. They had all agreed. There were hardly any people who lived in that place. Only two or three. After two nights, the kids kept waking up screaming saying that they dreamt about the forbidden castle. And that there was someone in there trapped. The next day I decided to check it out. But what I didn't know was that there were seven 3 years old's following me. As I opened the gates, I heard a screech from an old woman coming from up the hill. So I started running towards the castle. But I had to abruptly stop when I saw a random swamp pop out of no where. I decided to cross it when the sky got all dark. I kept seeing shadows passing me but I had thought it was my imagination. I kept going forward when I heard footsteps behind me. I felt my heart pop out of my chest and turned around only to see six of my day care kids. I told them that they had disobeyed me and the other s, and I had also told them to run away as fast as they could. I did not know at the time, that one of the children were missing. As I kept going forward, I started hearing one of the kids' voices yell in agonizing pain, but I saw no one around me. So I decided to go back to see if one of the kids got hurt going back to the town. As I was running, I heard the other s scream my name. I was running faster and faster. Once i got out of the swamp I ran quicker and got to the others. One of the s told me a kid was missing. I was then crying and I had no idea where to look. Then, black shadows were flying all around me and the others. The children were screaming. I told the other s to run to safety and I would search for the other child. I ran back up the hill, but the swamp was gone. It was a corn field now. So i ran through it, and got to the door when I saw the missing child's skin covering the door. I didn't what to do. Either run or cry. So I did both. Then I turned around and there was a black figure in front of me and I screamed and woke up.

What does this mean?
Btw: Usually my bad dreams like these happen, so what am I to do to stop them? ( The odds are about 1 out of 3 dreams happen).
