Ok So here are some Sunan for sleeping, I got these from Awnal Ma3bood by the way

:
Dusting Your BedPlace before sleeping
عن أبي هريرة قال
قال رسول الله صلى الله عليه وسلم إذا أوى أحدكم إلى فراشه فلينفض فراشه بداخلة إزاره فإنه لا يدري ما خلفه عليه ثم ليضطجع على شقه الأيمن ثم ليقل باسمك ربي وضعت جنبي وبك أرفعه إن أمسكت نفسي فارحمها وإن أرسلتها فاحفظها بما تحفظ به عبادك الصالحين
From Abi Hurairah, He said that Rasulullah peace be upon him said " If one of you goes to his
Firaash (place of sleep/rest) then let him dust it with the edge of his Izaar For verily he does not know what rested there after him. Then he should rest on his right side and say " Bismika Rabbi Wadha3tu Janbi wa Bika Arfa3uhu, In Amsakta Nafsee Farhamhaa wa In Arsaltahaa Fahfadhhaa Bimaa Tahfadhu Bihi 3ibaaduka As-Saaliheen"
Reading the 3 Quls and wiping over Body
عن عائشة رضي الله عنها
أن النبي صلى الله عليه وسلم كان إذا أوى إلى فراشه كل ليلة جمع كفيه ثم نفث فيهما وقرأ فيهما قل هو الله أحد وقل أعوذ برب الفلق وقل أعوذ برب الناس ثم يمسح بهما ما استطاع من جسده يبدأ بهما على رأسه ووجهه وما أقبل من جسده يفعل ذلك ثلاث مرات
From Ai'shah May Allah be pleased with her, That Rasulullah peace be upon him, Whenever he went to his Resting place everynight he would bring his hands together and spit into and read on them 'Qul Huwallahu Ahad' and 'Qul a3udhu birabbinnaas' and 'Qul a3udhu birabbil Falaq'. Then he would wipe with his hands all of those parts of his body which he could reach, starting from his head and face and the front of his body. He would do that three times
Placing The Right Hand under the Cheek
عن حفصة زوج النبي صلى الله عليه وسلم
أن رسول الله صلى الله عليه وسلم كان إذا أراد أن يرقد وضع يده اليمنى تحت خده ثم يقول اللهم قني عذابك يوم تبعث عبادك ثلاث مرار
From Hafsah the Wife of Rasulullah peace be upon him, That Whenever Rasulullah wished to sleep he would place his right hand under his cheek then say " O Allah Protect me from Your Punishment on the Day that you Ressurrect your Servants" three times
