Zontonnia,
The first part of your dream seems to be pointing to greater possibilities that await you once you realize and learn to utilize the power of those inner forces, spiritual and creativity. Here is how it plays out.

This is your inner classroom. On the outside it feels empty, without direction. But there are greater possibilities locked within. The task is to bring out these greater possibilities into the waking world. Achieving this brings about unlimited possibilities to your waking self. There are no barriers that can hold you back, the sky is the limit. Realizing and utilizing your inner 'greatness' opens up unlimited possibilities in your outer world.

In your waking life the barriers would be other people holding you back. Dragons are the social obligations and requirements. You have defeated one large dragon {this dragon may be realizing the inner world, one aspect of that being the study of dreams}. Your inner growth is how you 'manage' the outer dragons. The mother reference may be about personal relationships and/or she could represent you, as a mother and your own personal relationships with your bf. Spiritual aspects are a part of this equation. Your amour is up in defense of this vital aspect {are there conflicts within your family over your spiritual beliefs?}. You may also want to look at the word 'armour' as a connoting of love, amour, since your spelling includes both possibilities {armor and amour}. That may denote personal relationships with a male which in itself could be a barrier.

A bit off subject but while we are speaking of 'amour'. This reminds me of a poem Joseph Campbell often quoted, from the time period of the King Arthur tales of original romance in the Western world {previously all marriages were arranged}. It was related to the romance of Tristan and Isolde.
