I had a weird dream last night.  The focal point of the dream was that I was in a building with many people.  Some how I found myself climbing up into the highest tower.  No one below me seemed interested in climbing up into the tower, they were all content with being down below in the main building.  I am not sure if they knew of it but certainly didn't seem to care to go up the tower.

I climbed up though because I thought something worth knowing might be at the top.  I some how think what ever was at the top was forbidden but nothing made any attempt to stop me.  I remember vaguely at one point my breath was like ice up near the top.  Not like the fog of warm breath in cold air but my breath it's self was frigid and misty.  

I don't remember what I found at the top or anything that was said to me, but when I came back down I had the power to utterly devastate the world with a single word.  If I spoke the word the world would freeze and everything would stop.  I don't remember the word, nor did I have any desire to speak it.  I never would, I just know that I could if I so chose.

I also seem to remember something about a dragon egg.  It wasn't a focal point of the dream.  It was just sort of there.  In the background almost.  It was beautiful though.  It was about the size of my microwave and was glowing red and gold just like an ember in a fire place.  It was the same shape as a snake egg.

A bit strange.  Though I think the entrance to the tower might have been hidden.  Hidden rooms and secret passage ways have been a recurrent theme in my dreams since I was a teenager.  But usually there are  humans in these secret places with me. in this dream I was alone.  There might have been a presence watching me.  But it was not human and definitely not visible.

I have looked several times but have never found secret rooms or hidden tunnels in any dream dictionary.

If you look at what a room signifies in general and then think of that aspect of yourself as being secret or hidden, or something that might be subconscious.  Or even, yet, something you are keeping secret or hiding.
A tunnel is usually a passageway of some sort.  A spiritual passage, perhaps?  
A hidden door--hmmm.  The subconscious entryway to your spiritual growth and seeking?

farie it seems to me that you you still haven't found or unlocked your potental as of yet but i think this thing that you found at the top of the tower symbolizes magick it self within you. magick isn't good or bad in  it's raw form it is how use will it that makes it good or bad to create like the egg or destroy it is both and yet neather within each of us lies the power to create and destroy. i think that is what this dream of yours is trying to tell you.
