I'm the dimwit around here, but here's my penny's worth.
Is Mike really dead? Or is it the Mysterious' man metaphor that being a heroin addict makes him already dead? Or is this like the movie Hide? Is there something else I might be missing? I could very easily be missing the big picture.
Anyway, since the mother killing herself (she did right?) is a guilt trip that Mike's on, it needs to be mixed into the story early.
The thing with short scripts (what makes them so hard) is everything is shown in a short amount of time. So everything needs to be important and intertwined.
Breaking down this script (if I'm reading it correctly, and that's a big if)
1. Mike is being chased and killed in his dream.
2. Gets up and can't find any drugs.
3. Breaks into someone's house and steals drugs. See's stranger.
4. Buys food after getting high. Sees stranger, and chases him. Mike's knocked out.
5. Finds out stranger was sent to help him with second chance.
6. We learn Mike and mom argued over money for drugs. Mom killed herself.
7. Stranger kills Mike. Or Mike is already dead because he's a drug addict.
While these are the basics of the scenes as I see them. And again, I'm a dumbass sometimes (okay more then sometimes), but they need to be interwoven. Mike's guilt, the stranger actually trying to help him with a second chance, they need to be there from the outset.
With shorts, there's usually an AHHH moment at the end, when everything finally makes sense. That's not here, because each scene isn't really connected to the prior. To stress this point, where does Mom get mentioned, shown or thought of before the Stranger mentions her?
ALSO: I should never be one to point out errors in spelling and grammar. But there are quite a few. However, they didn't really kill the read, because you wrote simply, and it was easy to understand where you were going. But, things like Narrator should just have been Mike (VO).
