Come to my window?

My window has long been an alternate means of announcing arrival for late night visitors. The last two weeks however, there has been an alarming pick up of traffic, during the day. Last week it was more of a light tap and today it sounded as if someone were truly knocking on a front door, not a window. I bolted awake and asked who it was. No answer. I went to the living room and buzzed the door buzzer. Nobody came in. I went outside and tenatively called the name of the person that I thought it was. No answer and nobody in sight. I'm starting to get a little weirded out by this since it has happened three times in less than a week and nobody comes to the door. I have some odd neighbors so maybe that's it. But, if you or someone you know may have wandered over here and knocked on my window. Please lemme know so that I can stop worrying! Come to my window Crawl inside, wait by the light of the moon Come to my window I'll be home soon I would dial the numbers Just to listen to your breath I would stand inside my hell And hold the hand of death You don't know how far I'd go To ease this precious ache You don't know how much I'd give Or how much I can take Just to reach you Just to reach you Oh to reach you Come to my window Crawl inside, wait by the light of the moon Come to my window, I'll be home soon Keeping my eyes open I cannot afford to sleep Giving away promises I know that I can't keep Nothing fills the blackness That has seeped into my chest I need you in my blood I am forsaking all the rest Just to reach you Just to reach you Oh to reach you, oh
