Ofcourse. There is nothing wrong in wearing that. Even the Prophet(SM)wore a certain type of attire for sleeping.
However I'm not sure about rural Arab people,and many rural muslims in my country only wear the traditional bengali Lungi and tank tops. Only the modern,middle-class muslims wear Pijamas.
Salam Yes we Muslims usually wear pijamas when we are going to sleep.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
