Question In call strange music.

Hi guys,

yesterday i called my wife, then immediately after dialed number and pressed call button, i heard a strange music, something like a mid 80's mix of Tron music in an anxiety tone. I tried to call her several times and that repeated every time. It disseapeared when I rebooted phone...

Last thing I've done was playing clash of clans. but that sound doesn't came out of that. Nothing was running in backward.
So this is my question... has anybody ever heard or had something like that?
Or am I in a sort of Truman show ?

" Dear producers please give me a lot of money and a work I enjoy... "

Thanks for the answers...
