getting rid of bad habits gives you a murderous nightmare

in the middle of the 2nd week of the semester now, and I am wondering why am I doing unproductive things...

recently have been dreaming about murder and also some violent things. Was so curious so I googled what the hell did those nightmares mean.
Turns out it means I am trying to get rid of old habits and my brain works that way.
Old habits huh?
Is eating alot a habit?
Is procrastination a habit?
Is being lazy another habit?

These could all be true. As somehow I need to eliminate these habits.
