Am I normal?

I was once had problem sleeping at night. This happened few years back when I was still in college doing A-Level and it lingered for half a year. Though I had a bizarre behaviour of disliking sleep but due to human nature I could not help myself but to succumb to my biological needs.
It dreaded me anyway because I dont have enough sleep at night and have to wake up early in the morning to attend class. The only time I could sleep soundly (though not much) is in the afternoon.
I have no answer why it happened to me because I never consult with a doctor or psychologist for a proper analysis.
However I eventually recovered from the "sickness" a month shy of my A-Level exam.

Along the journey of recovery I have tried a lot of method to fix my biological clock and only one works best for me.

It is by fantasizing a role-playing game in which I am the assassin involved in a plot of killing his enemies. The scene is usually set in Iraq (or desert).
By doing this I will doze off in 5-10 minutes.

In reality I never hold a grudge against someone. Even if I am angry with someone I am sure it never reach to the thought of harming, let alone killing him/her.

Is this some sort of dual personality or something?
Psychologist help!!
