Would it be good for my spine to sleep in the pool?

I'm not a doctor or anything so I don't know what good it would do for your back, but it probably wouldn't be good for your neck. I think a doctor might suggest something less dramatic, like stretches you can do that help your back or you can buy a new bed? I don't think you should sleep in a pool because that would be like sleeping standing up. And I don't think it would drift your spine into the position it needs to be in. But you should probably call your doctor or whoever and ask them what you can do for your back.
