Should I go to bed tonight?

Today, June 25, 2014, something strange happened. I was home alone with my cat. Having suffered from insomnia since I was 12, I stayed up all night, and only around midday did I begin to feel sleepy. The sun was shining brightly outside. My cat lay down next to me, and we fell asleep together.

At three o'clock in the afternoon, I was awakened by a clap of thunder. A terrible thunderstorm had begun, and the rain was pouring down like a deluge. It was gloomy outside, and there were no lights on in the house.

When I woke up, I had a very unpleasant feeling. My cat was sitting on the computer desk next to my bed, looking frightened, his chest pressed nervously against the desk, wagging his tail. I lay back down, covered myself with the blanket, and then heard the distinct slap of raindrops hitting something. I got up, walked into the hallway... and was horrified.

 The front door was wide open. The sound of dripping water was coming from the entryway. I was scared. The door had been locked when I fell asleep; nothing could have opened it like that! I was terrified. I closed the door, and then I had a strange feeling, as if I wasn't alone in the apartment at all. I went back to the bedroom, lay down, and my cat hurried over and scurried under the covers. Incidentally, my cat is a rather unkind creature—he doesn't let anyone near me, and he treats me with malice, so why would he crawl under the covers now? This had never happened before.

Then the cat started meowing desperately under the covers, while in the living room the closet door creaked open of its own accord. "What the hell?" flashed through my mind.

Footsteps! Heading toward my room—rolling, loud. I was ready to faint from fear, but then I heard the key scrape in the keyhole. It was my sister returning from work. Immediately, I heard a commotion in the hallway, which told me the intruder had hidden in the closet.

I didn't tell my sister anything, as she's a confirmed skeptic. I peered into the closet with extreme caution—no one seemed there, but then I suddenly felt the feeling of someone very close again...
