What does this dream mean (friend got bit by snakes)?

The crux of the dream appears to be the calling 911 and them scheduling an appointment in 4 hours. This is a stress dream, and an easy one to spot. You are freaking out the whole time while everyone else is just having a normal day. Another theme of this dream I think is the expectations that were not met. Was it a part of the dream that you wanted to take your friend to the park? If it was, there was disappointment too. If that was just part of how you actually felt, then it just may have been the setting of the dream and insignificant.
