I had a strange dream that I was at the top of the tower, and then the tower fell down, which made me dream!

It seems that you are a very hard-working student. You always have high demands on yourself and constantly challenge new heights in your study. The collapse of the tower is just a kind of worry in your subconscious, because you may have trouble in your study and there is no danger to your life, so you won't feel very scared, but if you can cultivate your ability to resist pressure and setbacks and jump out of the predicament, your studies will definitely go up a storey still higher!
