My hotel and a friend needing help

felt like post apocalypse. Didn't write it down in my journal. so a bit hazy.

Was in a multilevel hotel with my son surviving and a friend (from SF) was needing help from me. a lot of the dream was centered around trying to start a big rig truck to leave the building. towards the end of the dream felt like me and my boy were racing to escape from her?

there was also a lot of importance on a specific part being needed and i had to fabricate a solution in the dream. If i remember correctly we did leave in the end.
