yara i was about to ask whether you live in close vicinity of a mosque. Couldn't really understand what you wrote :s but got to know that you live near a mosque, and i guess thats the reason why you hear azan at odd times. The sound waves kind of resonate inside your ear, cannot explain it to you but the main reason is that repeated hearing of azan from such a close distance is the reason why you hear azan at such odd times. I didn’t use to live very close to a mosque, but that maulana sahibs voice was quite thunderous LOL thats why even I used to feel as if someone is giving azan at quite odd times.
