Facebook ads INSTREAM

So please tell me i'm not crazy.

Just recently I started getting facebook ads in my stream. I mean every 4-5 posts in my feed was an ad... It was obnoxious. Then a few days ago they started being audio ads (surely PPP). I posted on facebook about it and all my friends said they weren't getting them. i did a google search and i saw articles mentioning them, so is this happening or am I crazy?
