Two nights before the Chilean earthquake occurred and set off a tsunami in the Pacific, I dreamt a man dropped my cell phone in a glass of water, rendering it inoperable. However, I didn't seem too upset about it.
The dream accurately depicted a waking-life scenario––one I couldn't have known about in advance. The man I live with was visiting friends in Hawaii at the time. Because of the tsunami, he was evacuated to a remote place inland where his cell phone didn't work. I couldn't help laughing at how my dream described the situation, and let me know there was nothing to worry about.
