Visit from a Spirit

I could barely move when I got home from work, I was so tired. It was nearly two o'clock in the morning. When I entered my room I felt a chill in the air, but I was so tired I didn't think anything of it. I laid down on my bed and almost immediately fell asleep. That night I had the strangest dream. I dreamed that two men dressed like monks came to me and said they had a message for me. I wasn't sure if I should trust them, so I stretched out my hand and asked them to shake it, and they wouldn't, so I knew they were serious and had an important message for me. At that point something jolted me awake. It took my eyes a long time to adjust to the darkness. I sat there trying to figure out what had woken me up, and then I realized I was filled with fear. I glanced down at the end of my bed and noticed a tall figure standing there. At first fear froze me, but then I decided it must be my brother Jeremy. I was angry and yelled, "Jeremy what are you doing?" The figure didn't move. I took a closer look and noticed that he wasn't standing on my floor, he was floating in mid air. I also noticed that he had his hands together and was holding a small black book. Again fear froze me. I didn't know what to do. I was still staring at him when he looked up right at me (It was too dark to make out any features of his face) and closing his book, turned and walked right through the wall. The wall that separated my room from outside. I was petrified. I shook for a long time and then eventually fell back to sleep. I have no idea why this happened to me, and I have always wondered if there was some kind of message I was supposed to receive that night. This stranger has never visited me again.
