I caught a glimpse of something that wasn't there

10 hours ago (10:26 PM now) I was walking from my Fiancée's (F) car to the garage and I saw something gigantic standing next to the garage door. <br>It was a looming figure taller than the garage, probably 15-20 feet tall. It had 2 huge red eyes staring at me. It didn't move, and I felt no movement. I felt like it was startled that I could see it and it was frozen in place. I watched it for maybe 2 seconds then I looked down at the ground. When I looked back up, it was gone. I didn't see it walk or run away, it literally just vanished. <br><br>I didn't mention it to F since we were both half asleep, I figured I'll just forget about it by the time I wake up. But nope, it's been bugging me for 10 hours.<br><br>What was it? <br><br>Does this relate to the glitch in the matrix?<br><br>Edit: I was NOT high at the time, but thank you for the offers.
