Spehere with BRIGHT red light, totally quiet. probably smoke-tail when flew away. duration 5-10 minutes. outside window.

Hi. Me and my mother saw a strange thing when i was about 5 years of age. My mother was around that time 31 years of age. We woke up in the night because of a really bright red light lighting up our bedroom. We lived three stories up (10 meters). My mother thought it was a brake light from a car. but when she and i looked out of the windows there it was. Throwing its light only into our room (so it seemed). i got really scared (5 years!) but my mother looked at it for this 5-10 minutes. she wont talk about it now so much because she cant explain it. The lights were BRIGHT red and it hoovered in total quietness. After these 5-10 minutes it flew away (still totally quiet). My mother thought she saw some smoke after it. As a tail of smoke. Well thats that. Nice to get it of my chest. This is true! i have no intension to write this much for nothing. I swear that it is true. But if it were alien or some experimental flying objekt of some militarty i dont know. I believe in alien 50 percent and military thing 50 percent.  Me and my mom believe it to be about 3-6 meters wide.
Date of incident is approximate.  PD
