This is a rather short segment of my dream... but it's what I remember the most so here goes.

I'm facing my ex girlfriend and i stare and she stares. I stop staring and she stops staring. Then vice versa.

I don't get it.

Since she is your ex, perhaps the words staring takes the place of the word caring. You stopped caring, then she stopped caring.

The vice versa part is interesting. Could it actually be a reversal of "not caring" to caring? Do you still care for her and long for a relationship with her?

I still care for her. The dream was even semi-lucid. I really opted to stare, just to see what she'd do.

We broke up a bit ago on rather unstable terms. You know, one of those indefinate kinds of breakups where you don't know how strongly she feels about her decision... but you also know that her mind is totally made up.
