Travel is an option

You can find yourself walled-off suddenly or gradually. Your world is shrunken down and depopulated. You could accept this as the new normal. Maybe it's just a matter of lacking the energy required to break out of that perception. 

In the dream, you were traveling for work. You were having a drink with two other people while waiting for your dinner to arrive. Presumably these were new and temporary co-workers. The restaurant was on the second or third story, had partial red brick walls, but was largely open to the elements. There was a light ambient fog. As you were chatting, a clear wolfish howl rang out from somewhere close by. Without hesitation and in solidarity, you howled in return. As you finished, you could hear other responding howls winding down. No one laughed or made a big deal about it. You thought maybe this could be a good place.
