A strange vision from one of my dreams

I wondered if it was true, if what I was seeing was real. My caller ID, the one on my phone and not on my TV, showed, and was in red this time. I didn't pick up as this seemed like a dangerous idea. The next thing that I knew was being in a store where I've had negative experiences, and I was in line at the cashier's station, behind someone who was trying to pay. I started peering at the display next to the cashier that usually indicates the total amount that the buyer needs to pay; and instead of seeing their total amount, I seen a message, and it said: "Pick up your phone"...in RED letters
