According to Wikipedia, a Dissociative Fugue state is when someone has lost all memory of themselves, including name, personality, and connection with others. And So...
You are Fugue!
Decisions made by "you" are handled by suggestions (it leads to Fun!).
You have one life, don't squander it.
Anything that can be attributed to chance will be handled by a 1-20 roll on random.org.
You are still human, and have limitations, don't overdo it.
You can't really remember how you got here, or where, exactly, "here" is. Around you you see a large pier down the beach.
You're lying in sand... Huh.
Somewhere you can here a fire crackling. What time is it?
AARGH! Your head aches worse than it ever has. The last time it ached was... Er... Nevermind. Thinking hurts.
AGH! What's with these cars! Stop driving so loudly! Ergh. Hung over... Alcohol was involved somewhere along the line.
Okay... self... can't remember my name.... damn...
No! No distractions! Assess self!
Okay. You're wearing pants. This is a good thing. You can move all of your limbs relatively well. Good. You can't remember a damn thing about yourself or anything around you. Hmmm. Oh well.
You are reasonably sure you live somewhere within 10 miles of here. How could you have gotten here in the first place if it were further?
Agh...
Suggestions! What will "self" be called?
