Nightmare

It wasn't a dream... but it was worse than a nightmare. I woke up few hours ago thinking that it's already the next day, and with the sudden thought that I lost someone very important and dear in my life... How I wish it will not happen for real. You know how's the feeling like? It's just as though you lost everything, as in everything about that person... memories, thoughts... smtg like that, as if you don't know that person or never met her/him before. Zero memories of them. Now that's a scary thought.
