I heard that a sleep measuring machine is available these days. It says that the machine can visualize your sleep condition. All you need to do is to set it under your pillow and sleep.
I think my sleep condition isn't very good, so it's interesting for me.
I wonder if it will help me out to lead the deep sleep.
