What is something that you thought was a simple everyday thing that wasn't until you found out

I'm currently sitting here in tears right now, so I just want to start off by saying I'm sorry if this seems unimportant, but I found something out about myself that I just can't seem to get over.<br><br>I've been a heavy sleeper my entire life. I don't remember much about my childhood, I don't remember waking up in the middle of the night, and I don't remember much of anything until I was about 9 or 10. I've never been woken up in the middle of the night by anyone and I've never had to wake up anyone else in the middle of the night. <br><br>I'm a heavy, heavy sleeper. I can set an alarm on my phone for 5 minutes from now, fall asleep, and then wake up at the exact same volume when it goes off. I'm not even exaggerating, it's crazy. <br><br>Until today. <br><br>I'm currently in the process of buying a house and the people selling the house decided to let me live in it for a few weeks before they close the deal. I've never been here before and I don't know much about this area at all. <br><br>I brought all my stuff over here and then drove to my parents house a few towns away. I stayed at my parents house for a few nights, and yesterday I drove back to this town and to the house I'm buying. I was super tired, so I decided to take a nap on the couch in the living room. It's a really big house and it's empty, so I set up cameras and alarms around the house. I felt pretty safe. <br><br>I fell asleep and when I woke up it was 3am. I thought maybe it was sunlight or something, but it was pitch black. I went to lay down on one of the beds to sleep and I woke up at 10am. Still completely dark. <br><br>I'm so scared. I feel so violated. Someone has been in my house while I've been sleeping, and I don't know when they come or how they get in. I feel so violated, it's like I just lost my entire privacy. I haven't been able to shower or eat or do anything because I'm so terrified. I want to run and hide. I don't know what to do.
