The scariest thing you have ever woken up to?

Thinking someone was breaking in - very scary.

A good few nights/ mornings I have woken up to spiders/ rats/ serial killers/ cats attacking me. It's also known as the DT's - super scary.

my own cabbage gas after an indian and loads of guinness

A strange cat on my dressing table,scratching it with her claws.She got in an open window downstairs.I subbose Im lucky it was only a cat!!!

Both legs cramping like a motherfluck. Ouch.

Forgot one.

Woke up in the middle of the night to a storm. A proper midsummer Canadian one, not some dinky little Irish storm. Thunder loud enough to deafen you and make your stomach turn upside down and lightning making the world visible for miles. I had an old tree outside my window that my mother was convinced would get hit by lightning and come crashing down on me in my sleep.

Its branches cast shadows on the ceiling, like old, gnarled hands and demon faces on the walls. Without the lightning there was complete pitch black darkness. No moon, no stars. I couldn't see my own hand in front of my face. I got up and stumbled my way to the light switch, only to find the power was out. I went for the door, but for some reason it was stuck, something was holding it from the outside.

So, like any normal 18 year old (at the time) I went back to bed and hid under the covers, as you do.

Then I heard it.

I had this old wooden bedframe, the headboard was massive and about three feet high of solid wood. It was faint at first, but I could hear nails slowly, slowly scratching their way down the headboard. They came down to what would be about an inch above my head and I sprang out of bed, my heart pounding in my chest, about to burst.

I tried the door again. It was still being held closed from the outside. I couldn't force it open. I was freaking out. I heard it again. Nails, hard, against the headboard. I waited with my hands covering my eyes, fingers parted-- looking but not wanting to, as you do-- for the next lightning strike to reveal the nemesis I was now trapped in the room with.

I hadn't long to wait. A strike of lightning went off, and I was faced with two sets of pitch-black, vacuous, soulless, evil eyes...

I tried to open the door again, and this time it swung open with ease, and I was faced with a hulking black shape, emitting a low, menacing sound from the depths of its very soul, its eyes flashing red in the lightning. I nearly jumped out of my skin, sure I was now face to face with my reaper and bound for the deep, dark recessions of hell..

I didn't sleep at all that night.
