This morning, at about 4:30 AM, I was awoken by a jab in the right arm (I was laying on my left side facing the window), which is how my wife will often wake me up since I wear earplugs at night (which she doesn't like, so it is often not a friendly jab, not rough or painful, but not gentle). When I awoke, I saw a face toward the bottom of the bed, not on the bed or at the foot, but a little off to the side of it, directly in my line of sight. The face was very square, seemed a little larger than normal, and I could not make out the details surrounding the face (i.e.hair and body), even though it seemed like they were there, but I could clearly make out the features of the face. I had enough awareness to count how long I could see the "ghost", as it was clear that it was not real and it would probably go away soon. After about 3 seconds, the face started fading away, and after 5 seconds I couldn't see it at all. I looked around the room and nothing else was strange. The dogs were sleeping and were not making noise (I couldn't really hear them breathing because I had the earplugs in), so it did not seem that it was something else that woke me up. At the time, I could remember my dream and there did not seem to be anything in my dream that would have woken me (like often I will be woken by a loud noise or music or a sense of falling in the dream). Also, the person that I saw was not someone from the dream. I can no longer remember what the dream was about.
I took out the earplugs and could not hear anything either. After putting the earplugs back in and lying down to try to go to sleep, I could not go to sleep quickly. I tossed and turned for a couple of minutes and then decided I had to go to the bathroom, so I turned the light on at the bedside table (I never do that at night, but since my wife wasn't home, there was no one else to bother with it). After going to the bathroom (turning more lights on along the way) and taking a good look around the room, I climbed back into bed (all the lights off again). On the way back, I looked for the pen and paper that I normally keep beside the bed to make notes, but I had moved it a few days before and it was no longer there, so I didn't write anything down (otherwise, I would have been better about remembering the dream). After a few minutes, I was able to calm down and fall back to sleep.
I don't believe in ghosts, and it was clear to me, even at the time, that there was something going on my mind that resolved itself by telling my brain that I was seeing something that wasn't physically there. However, I freaked out enough that it bothered me enough to have trouble going right back to sleep. It was what you can accurately describe as "weird".
