Strange Happenings Part 2

First, last night's weird chain of events, then today got even wierder. It started off at the grocery store. I was picking up a birthday cake for this weekend's quiet festivies, and as I'm putting my things in the backseat of my car, this weird guy pops up out of nowhere and says "Can I give you a hand with that?" in what I would consider a creepy voice. I just said the casual "I'm good, thanks" as I turned back to my car, and mentally prayed he wouldn't stab me. He said nothing else, so I figured he'd left, but I didn't dare look. I grabbed the last bag and tossed it in my car, and as I turned to take my buggy back, I saw that creepy guy had beaten me to it. So, before he could come back, I jumped in the car and took off.

Then, after I came home, I got 4, maybe 5 hang-uppy phone calls, and then I got an email from "Nobody" that simply said "adf". What's going on? Am I being called out by some weird force? Things are starting to look very X-Files..... Which reminds me, Monday some guy behind the Salvation Army tried to flag my car down, in what appeared to be an attempt at selling the contents of their dumpster. He had those crazy-man glazed eyes and practically jumped out in front of me. I could see him yelling something and pointing at the dumpster, but have no clue what he said. Oh well.
