I read an article recently about a lot of people who hear phantom phone ringing (myself included) and even feel it vibrating on their legs when it's not attached to them.
i've gone through times of hallucinations...hearing people knocking at my door, lights flashing, objects moving....always when my sleep is really messed up so I'm wondering if your lack of sleep is adding to that.

I'll try to find the article for you.

You guys are not the only ones for sure!
