earllusion - When you're so out of it that you think there's a whole part

When you're so out of it that you think there's a whole party happening, but you're just alone with your stupid thoughts.

I thought I was at a concert, but I was just in my room with my dumb ideas.

I believed I was in a big fight, but it was just my brain being a jerk.

I thought I was in a restaurant, but I was just eating cereal at 2 a. m.
