This was a dream I had about 2 years ago. I had been telling myself I would get back into lucid dreaming, and was regularly checking my surroundings for anything odd. In this dream I was in front of my garage, about to type in the password to open the garage door. I turned to look at my friend I hadn't seen for a long time in real life, and he was on the ground looking up at me, crawling without legs. There was something about it that reminded me of a cockroach. I was looking at him thinking "something isn't right here" trying to work it out in my head. I turned back to finish typing in the garage door code, and when I turned back he was normal, standing on two legs. I had that feeling you get when you were thinking about something important, but forgot what it was. I dismissed the feeling and woke up dissapointed. A similar experience happened more recently, a couple months ago. I was in line paying for something, I think it was fast food but the window was more like a what a bank teller stands behind. I payed for whatever it was I was getting, and the person behind the window said "do you want a body bag with that?" I was confused but dismissed it. Immediately after dismissing it the person behind me in line asked me "Do you think that was normal? Wasn't there something strange about that?" I ignored the DC. It's the only time I've had a DC try to tell me I was dreaming.
