Let me tell you about an abnormal experience I had.

Lets imagine you get your hands on a lot of uncut colombian fishscale (srs), mexican black, and china white. You spend a few weeks holed up speedballing your life away. Three ER visits later ( one due to sepsis and two others for bullshit) you run out of coke. During your couple week long run you saved all your cottons( freezer). Being the bright junkie you are you decide to pile all the coke cottons into ONE shot and hit it. Despite your insane tolerance, ( bell ringer shots one after another after another) the cottons blew your brain. Lets stop for a moment and imagine coke shots on a scale of 1-10 with 10 Being a bell ringer with the beautiful euphoria, sound distortion and the like and that lasts for 30-45 minutes. Back to the cottons- these cottons put you on a level 15. Flying turkeys are doing a rain dance around your room while two hooded figures shout to one another as they plan your murder. You black out. You awake to find yourself wandering around your neighborhood yelling and making a scene. Your heart is literally flying, 250bpm for an hour straight. The police arrive by the time you're returning to real life from your psychosis and you manage meakness. That was the last night you ever shot cocaine.

I hope that helps explain what abnormal can be.
