The meaning of the term "soul" is somewhat variable. In the ancients, it is the same as mind, the part of you that thinks and feels. Combining that with modern science, the soul is some of the processes of the brain. This makes the soul like the "harmony" that is discussed in Plato's Phaedo. And, generally, it dies before some other parts of you die, before all of the cells of your body are each individually dead, your mind is gone.
Any other story you are going to hear about the "soul" is likely to be bullshit.
