I have a good idea what this is about i just wanted to see if anyone else had a thought. ive had this dream since i was about 8, im 16 now. But i haven't had it lately.

Im standing on a book shelf in the library (i am very small) and there is a lion sitting on the shelf too (about two times my heighth). i run up to it and it knocks me off the shelf and thats where the dream ends...

Do you have a reading disability? The lion could be a symbol for the overpowering struggle you have with the printed word, that is if the interpretation fits.

No, i don't think the dream has much to do with the actual library.

My Previous boy friend's zodiac is Leo the lion and we had lots of fight. He was very mean to me but i stayed with him. i thought it was fate telling me or rather warning me that he was going to hurt me... maybe, because i haven't had that dream since we started fighting.

That makes sense. The best person to determine what a dream means is the dreamer him/herself.
