When we are dying, will we see Malak al Maut as we lay in our deathbed or is that a myth? Also how is it possible that he's takes the souls of multiple people around the world at once? Is he the only angel that takes the souls or is there more? Jazkallah for whoever asked this question, answers it or even views it. May Allah swt guide us all and bless us with jannat al firdous allahuma ameen.
For every soul, there is a separate Angel of death:
Say, “The angel of death who has been assigned for you will take your soul in full, then you will be brought back to your Lord.” - [Quran 32:11]
And about whether you will see angel of death on your deathbed or not, you will only know when you will die.
