are there people who actually sleep on just one layer of pillow or is the pillow industry just trying to increase sales by lowering the plushness of its pillows
I have three pillows, and I also use one of those sitting up pillows, partially for reading, but also to prop my head up when sleeping. Also, when I sleep, I tend to cram the blankets behind my head too, not intentionally. Once in my sleep I tried to cram the dog behind my bed, which of course woke both of us up.
I have two pillows, technically three if you count that I also have one of those wedge-shaped pillows that make you sit up in your sleep cause if I don't then my acid reflux strikes and wakes me up >:L (I won't go into detail xD)
