Nightmare

What does it mean when one has a horribly vivid nightmare, about terrorists and fire and mass death and crashing planes. And you are the passenger in a fleeing vehicle as planes and buildings fall around you. And your dream self closes her eyes to the terror and begins sending metta to all beings. With a foreknowledge of imminent death, and with fear very present, my dream self could only send metta, to the terrorists, to her family, to the victims, to all beings everywhere.
Now, in a dramatic analysis, I could say that we are all these passengers, flying toward our deaths, there is no way to change or control our destiny with a hopefully peaceful, but possibly sudden, violent, or painful death. It is inevitable. And yet we calmly plod along, I will sit tomorrow, I will send out metta later, I can't send her metta she is a bitch, I am too pissed off for metta today. I suffer from all of these maras as well.
Here again I am pointed to the quote "practice like your hair is on fire". Why is it I see this, I hear this, I smell this everywhere, and yet I struggle so much with  laziness?
