Sleeping in a hammock

The conditions need to be just right to get a good night's sleep but it's possible and actually quite restful. There can't be any bugs about, not too much wind and the temperature should be around 20/70. All the planets were in line last night so I slept fitfully until about 3am listening to the waves break on the rocks and sandy shore nearby. After that I could not get back to sleep because I couldn't lie on my stomach.
