Two Year Old child's dream

So for a long time I have had this dream in my head. I was two years old and living in the Ypsi apartment before we got the house in Ann Arobr.

I walked out of the of the apartment while everyone was sleeping. I had a sense of urgency to get down stairs. I remember the walk down the those stairs like it was just last night. It was long and hard to get down. But I got it after a time.

I saw this door at the bottom of the stairs, a big old and almost scary door. I couldn't open it at first. Open and cold, this room I saw through the door was not a happy place. All brick and slimy like a dungeon. For what ever reason I didn't see this when I first walked in, only when I faced it.
There was a large, vary large, Lion pacing behind a even larger prison cell. It was big enough for me to walk through if I wanted to, and I did. But the Lion saw me and tried with all it's might to attack me, to kill me. Like I was the one that put him there.
It was loud and cold and even more scary, but I wanted to let him out of that place. I wanted to set him free. I went to let him out a few times but he was too big and mad and if I would have gotten to the door he would have got me, killed me. But I tried a few more times and stopped. I just stood there looking at him, trying to get me, and cried. It was so small in comparison to him.
It felt like he was of a "good" and something of a "bad" put him there. I could not set him free. I could not save this Lion that felt like my brother. So I woke, crying.

That Lion must still be in that prison today.
