What's a mess?!

My "tiny" bedroom and washroom are in a mess now.
Many papers spread over the table.
Many clothes spread over the bed.
My belongings spread over the carpet.
Yet I have no intention to pack or tidy up any stuff.

I predict I needa burn mid-night oil on the last nite.
Please remind me what I MUST bring back.
I am pretty afraid my brain can't function well at that packing moment.
