Every now and then, I suddenly have a feeling that I have been in this exact situation. But instead of lasting for just a second, it lasts for a couple hours, and I start calling out exactly what's going to happen next. I literally remember every detail about that exact moment, before it happens.

I'm sorry if this advice is bad but that's what my friend told me and he is incredibly smart so I thought I would share his thoughts with you.
