Stayed in a holiday apartment in Prague. The first door led onto two apartments, both unlocked when Friend and I arrived.
We assumed it was OK to use the showers in both apartments but the manager went ballistic and accused us of breaking into the adjacent one.
I shrugged that off. We hadn't done anything of the sort so I assumed someone had forgotten to lock up.
We stayed Monday-Friday and every night when we were in bed I saw someone open the bedroom door and lean in towards me. Whoever it was had on dark clothing and was wearing a hood.
I assumed I was dreaming the first night but remembered the mysteriously unlocking door to the other apartment and decided to jam the bedroom door with a chair.
It still opened and my visitor and leaned in as before.
This went on every night until the last, when I awoke in the early hours and decided not to look towards the door.
This time I felt an ice-cold hand slip into mine and hold it for about ten seconds.
Line, Even if you don't want to see me, I'm here!
None of this fazed me. I told my friend about it and halfway through the week offered to swap beds so they could see it too but they politely declined.
