On the other hand, in I Am Legend:
There's a scene where Will Smith's character searches for his dog. We don't know where his dog is, or what's around the corner, but we know that it's dark and scary. We see blood - is it his dog's blood? We don't know, but we hope not. We wait to see, on the edge of our seat, waiting to find out if the dog is dead. Not Dramatic Irony because we don't know what's around the corner, but plenty of suspense.
Nice examples. Dramatic irony is a literary device we can use to create suspense. (And we may use dramatic irony to create other feelings in the audience)
In your second example, suspense is created by another technique.
Does that technique have a literary name?
