I have used the 'wind chimes' alarm sound on my iPhone for long enough that, when real winds picked up overnight, trigging the real wind chimes our next door neighbor installed, I woke up repeatedly. Several times. Each time assuming it was the phone in the other room, each time being too tired to get up and turn it off, falling back asleep only to be awakened again a little while later by the same damed subconscious trigger.
