Dreams are metaphors the mind creates to tell us something. It doesn't tell us the direct truth. It puts the truth into metaphors.
So don't interpret the exact imagery, rather, interpret what they represent and the feelings you went through. The message is in there.
You waking from sleep inside a sleeping chamber next to other sleeping chambers (4 or 5)?:
Does your immediate family have 4 or 5
I sensed that the other sleeping chambers were empty?:
Your family isn't around or are oblivious or are ignoring the obvious. You alone are
waking up to something and feel alone in this knowledge.
You're in a laboratory?:
You have a sense of stability despite your families current shortcomings.
Monitors showing that all over the world zombies are attacking?:
You are aware of the outside threat.
Bridges being destroyed by humans in attempt to stop the spread of zombies?:
Others are taking precautions, but your family has not.
Zombies come running into the lab from the upper level?:
It's too late, the outside threat is now inside and has the advantage.
You jump back into the sleep chamber?:
You don't want to confront this threat, you want to just ignore it like your family is.
Did one of your parents or siblings recently "remarry"? Is there a new "step mother"/"step father"? Or...does someone in your family have an
addiction that everyone is ignoring?
Or am I over analyzing?
Perhaps you just watched the movie 28 Weeks Later?
