Avoiding The Funeral

I was driving along to a funeral dry run, ie without the body. I attended the church service and all went well.
The next day I drove towards the real funeral, passing hundreds of parked cars and people heading for the church. I couldn't face attending so I slowly edged past the crowds, hoping I would not be noticed.
Just past the church I entered a white paper tunnel that spiralled downwards for around a mile.
I drove slowly down and near the end, walked the rest into an underground town.
It was a spooky and scary place, old shops and house with unknown doors and tunnels leading off the underground street. All totally deserted.
I knew finding my way back would be problematic.
If I did find my way back I surmised I would find myself back at the funeral.
No escape.
