Is it normal i saw my own eyes out side the window.

I was sleeping with my girlfriend last night, I woke up about 3 o'clock in the morning. I could not sleep so i stare in the wall of the room, then suddenly a image of eyes appear in nowhere. Thinking that it was just my imagination I try to look away, I look outside the window, and it was there, it was like my own pair of eyes so I prayed and it was gone. After it was gone that is the time where I look at my cellphone and learned that it was 10 minutes past 3 at the morning. Who was it ??? could it be a ghost or something ?? I try to search something in the internet but could not find anything related to it.
