You live inside a small apartment, surrounded by a number of either inconsiderate people, or old neighbors you've known for a long time and are good friends with.
Everything was normal, you had a long day yesterday, having appointments to go to, so you were knocked out. But due to your crappy sleep schedule, you ended up waking up at 5am. No worries, just watch something for a bit and go back to sleep.
You had your headphones on, younger, 7 year old brother sleeping on the bunk bed above you. You can hear his snoring through your headphones, so he hasn't done anything.
The snoring is still going, just as the sound of... Hooves, is heard for a few seconds, before stopping, and the star projector you and your brother have as a nightlight clicks on. You just figured your brother woke up to turn on the projector, but you realize, he never stopped snoring.
It was raining heavily outside, so you ruled out the 'hoof noises' as the rain on the roof.
The apartment was small, so nothing could really hide in it, right?
