I -would- have said Animus...IF there was an animal being threatened and not a person. The animus is a souble meaning in dreams as it also relates to the primal part of your psyche. In this case, t's not the animus but simply the masculine parts of your personality. It's what you see of yourself that is more "boylike".

For the record (you can ask Triciadrich and JustDon'tAsk this) - I. <3. Dream. Interpreting.

It's never a problem for me.
