I am not sure if this is a joke or not. This Quantum Sleeper touts that it is great for sleeping because it protects you from storms, attacks, biochemical warfare, kidnappers and bullets. It has its own built in entertainment center, microwave and refrigerator but I am not sure it has a bathroom. Gives new meaning to the term "sleep tight".
There are many good ways to have a secure and comfortable sleep without building and lying in a bunker. Some say warm milk before bed helps bring on the z's. Others suggest calming scents via aromatherapy starting with a slow relaxing bath with essential oils of camomile, lavender, neroli, rose, marjoram and/or geranium that you can add to the water or gently inhale. Also drinking camomile tea before bed will help bring on a restful sleep.
