WTF happened last night?

ok so last night I was in my room in complete darkness listening to some catchy tunes. Then I felt really…cold.. and uncomfortable so I went out to the living room (basicaly the whole house was dark) My mom was in another room (the office), and the light shined over towards where I was. I looked at my shadow and instantly wanted to go hang myself, so I raced back to my bedroom and begun the process but stopped myself
Why’d this happen? I could barely control myself, so maybe it was an impulse of some sort?
