Guardian Angel? Nuisance? Too Much Cheese Before Bed?

So there I am, lying on the sofa of my small annex flat. The calm is soothing after the chaotic month I've had, arranging the funeral of my stepfather. Being the most logical and "sensible" of the family, I automatically took control of the situation and moved in with my mother temporarily after his death, which undoubtedly delayed my own grieving process. So now I'm enjoying the peace and quiet of my own space once again, and I fall asleep.

I'm in a peaceful sleep, I can hear the TV in the background and I drift off deeper... Four hours later, I'm woken to a girl/young woman with a soft voice calling my name. It's not this, which immediately wakes me, rather me offering my reply to which the voice doesn't respond. I sit up, the TV turned itself off hours ago but the lights are still on. I look around and call out again but there's no answer. I think nothing of it and go to the bedroom and sleep right through undisturbed.

This happened almost every night for a week!

After a while the voice goes, coincidently around the same time as my mother can bear taking my stepfathers ashes from my place.

Weeks pass uneventfully and one night my (then) girlfriend stops over. It's well in to the night/very early morning and we've been in bed for hours. I find myself being woken up by that (now familiar) voice. I feel calmed and soothed by it, almost as if I actually know the voice but I can't picture the owner. I open my eyes but I'm unable to move. I'm lying on my side, staring in to the middle of the room and my (then) girlfriend is on the other side of the bed facing out. I notice a petite figure making their way in to the room. She has long brown hair but no face. She's wearing what appears to be the cliché long nightgown. I still can't move! I watch as she slowly walks across the room. I try closing my eyes but I feel like I'm wide-awake! I open them and she's right on top of me, by the side of the bed. She slowly crouches down and I still can't make out her face! The area where her face should be is now two feet away from mine, her head tilts to one side as if to look at me curiously. I don't feel alarmed, I'm completely congruent and at ease. Then, without warning, her head jerks forward, her hair parting revealing a demon-like face (like the librarian in Ghostbusters) and she growls in an instant right up close to my face. I close my eyes, take a deep breath, open them and she's gone. I'm filled with sheer inexplicable dread so I get up and walk through the flat for peace of mind. Nothing! I get back in to bed and (eventually) go back to sleep.

A year has passed, again uneventfully. I am now in a new flat, this time I'm living with my (now) girlfriend. Recently I've been woken up by the same calming, familiar voice. One night I remember looking out over the end of the bed, through the bedroom door and out in to the hallway. I see the back of a familiar female shape playing with/moving things around on the unit outside the door. I watch for a while before going back to sleep. Looking at the unit come the morning and nothing's altered, nothing's moved or changed!

Last night, I was woken up by someone physically touching me. It started with a soft touch to the nose, which woke me up. Then later it was my right leg, again I woke up. Then later still it was on my head. I remember previously being woken up by a pretty violent blow to the head a few times before - waking me with such a jump that I've almost fallen out of bed! Not a punch, more of a light, open-palmed tap but obviously add the "jump-factor" and the fact that it's the head, makes it seem worse than it is!

I know it wasn't my girlfriend, she was all the way over the other side of the bed and I was practically hanging off my side.

I've purposely tried to keep this a balanced story, to not give away my persuasion on the matter but I'm interested to see what you guys think of this.
