I always find it hard to sleep in a new place. Last night I was trying to sleep at an airport hotel. The bed was comfortable but the room made strange noises. I could hear the sound of water running through pipes. I could hear the electrical hum. I could hear the fans used for cooling. All of these are sounds I can cope with but the mystery creaking disturbed my sleep. It’s not regular or rhythmic and I still can’t work out what is causing it. I can’t even tell what direction it’s coming from (though that does suggest that I’ve been sharing a room with multiple creaky things.)
I turned off the air conditioning at around 3am, in case it was the culprit, but now the room is just hot and creaky.
