There’s no reason to sleep curled up and bent. It’s not comfortable, it’s not good for you, and it doesn’t protect you from danger. If you’re worried about an attack, you should stay awake or sleep lightly with limbs unfurled for action.”
For members of targeted groups, the initial impulse is often to withdraw, to go into hiding. Yet when it comes to both individual and collective self-preservation, it can be wiser to act assertively at the beginning, while it is still possible to influence the course of events. Even if this goes badly, it can be better to bring the conflict to a head immediately, before one’s adversary becomes more powerful. If nothing else, this strategy has the virtue of making it impossible to lull oneself into a false sense of security while the threat increases.
