Study Of Life After Death

What happens right when someone dies in Islam? ?

I’m still in the process of studying Islam and the life after death is intriguing. But what happens to a person right after they’re died, before they’re buried. Are they aware of their surroundings? Do they know what’s going on until they’re buried? And then the 2 angels will wait till everyone leaves to question him/her?

Can someone go into detail for me. Or any sites?
Oh, and are you alone in your grave until judgment day? Or can you see others?
