I've reported about entities in my room before but this time they seem to have affected every thing electronic in my room when it came. It was about 8 foot tall and about 4-5 feet away. The time of the occurrence was around 1PM, my watch stopped at that time. It stood there for between 3-5 minutes before turning around and slowly vanishing. Once again, my dog did not react to it being in the room and the other dogs that I now live with didn't react either. I did not see anything that looked like a craft when I looked outside nor did I see what looked like a landing area. My cell phone hasn't been able to hold a charge all day and went from about a 90% charge (had been off the charger for 2 hours) to a "critical" charge (less than 10%) just over the time frame of the entity being in my room.The entity was a dark green, almost black, with vertical pupils and yellow colored eyes. It had 3 ridges on it's head, one down the center and one on each side just over where the ears would be. Its mouth looked somewhat like a muzzle but was more blunt and wide. It wore a tan colored uniform with grey stripes down the sides of the pants and in insignia that looked like two triangles pointing at each other at the tops.
