Is this a sign? Please help?

Okay so recently, I've had these coincidences. Like just now, I was listening to pandora and an AutoTrader commercial came on, and at the same time, I looked at my yahoo questions feed and the first qeustion was "will autotrader work for me?"

I'm officially creeped out because this has been happening ALOT

And what I'm also freaked out about is that I was looking at a qeustion about doppelgängers and I didn't know what they were so I looked it up. And right after the AutoTrader thing happened. Maybe the autotrader thing was a sign that two things came at the same time, and there are two of me at the same time.

Is this a sign? Do I have a doppelgänger? These coincidences have been happening a lot lately, maybe like three in the last month.

And I paranoid or crazy or something? Or this a huge coincidence?
