It was right at the beginning, i am afriad of the dark but i dimmed my room (not made it as dark as possible) and i just started freaking out idk why though!

I have listened to the QuickHappy and Content doses, but today when i went to go use content again a sudden fear rushed over me. I dont know why but i instantly threw off the headphones! Can anyone help me? Ive used it before so i dont know why i have a fear all of the sudden...
