When I was about 6, I went through a phase of thinking that a giant wanted to kill me. I would lay in my bed and I could hear the giant's footsteps walking up the hill to our house. I would jump out of bed and peep through the curtains to see him, but of course, he was too quick for me and would hide.
When I got back into bed, it would start all over again, only he would be walking faster and faster and eventually running to get me. I really had trouble sleeping for a while because of this giant.
I don't remember how long it went on for, but I eventually realised that it was only my heart that I could hear as my ear was pressed tight against the pillow, my heartbeat getting faster and faster the more scared I became.
