Got about 5 calls within 24 hour period including odd hours of 5am and 8:30am. I rejected calls and finally answered at 12pm today. Caller was difficult to understand, but said he found me on the internet, that I might be his "dream come true", and that he just wanted to "be a friend to [me]."
He couldn't specify where he got my number, but said his name was Kevin. I told him my fiance wouldn't appreciate his call or my being his friend and I said goodbye and hung up.

* the call showed up on my phone with an extra digit, so the full number was 231-778-31404.
