I had recently gone through a breakup, but due to my financial situation, I was still sharing an apartment, a room, and even a bed with my ex-girlfriend. She and I kept different schedules for the most part, but there were often times when we'd wind up sleeping next to each other. This honestly wasn't as awkward as it sounds, but it did make for some interesting experiences... particularly when I did one of the creepiest things I've ever had the embarrassment of admitting to.

I'm not usually prone to any kind of sleep-oriented shenanigans, but one night, I sat bolt upright in bed, looked over at my ex, then leaned down and stared intently at her. At the time, it seemed like there was something I had to figure out, and the only way I could do it was by carefully examining her face. I mean, I was drilling into her with my eyes, I was staring so hard. The position I was in was uncomfortable, so I supported myself by placing one arm on either side of her. From across the room, it probably looked like I was getting ready to do something uncouth.

Well, I was close enough that the sound of my breathing (or maybe the feel of it) woke her up. She saw me staring at her and screamed... which woke me up. I blinked a couple of times, trying to figure out what the hell I was doing.

"I was, uh... I was looking for..." I paused, unable to remember. "I thought I saw... there was..." Nope. Nothing came to mind. I had literally no reasonable explanation for going all creeptastic on her, so I finished by saying "I don't think I'm actually awake."

"No," she replied, visibly irritated, "you're not. Go away."

We both rolled over and went back to sleep. The next morning, I remembered the above story, but she did not.

In retrospect, telling her about it may have been a bad idea.

TL;DR: "No, you're not. Go away."
