i sleep on my left hand side when i am getting ready to sleep. I did discovered that my saliva will slip down to my cheeks when i am sleeping. hence, sometimes, i would sleep on my back with pillow on my chest then a blanket to cover me up. My mom said sleeping on your back, you will have hard time to breath because spider is clamping your heart. So, i used pillow to block the "Spider". Weird, isn't it?
