Illusion Phantom: Freddy's Hotel

After his terrifying job at Freddy's hotel Mr. Williams decided to retire as he had constant paranoia of animatronics and he absolutely refused to buy robots to serve him as technology evolved.
Every time he saw one he kept as far away from them as possible and kept his distance. His brother Francis gave him one as a gift once and he ended up throwing it away it was a dog animatronic that could do tricks, that's it, that's all.
This whole paranoia gave him headaches, nausea and sudden bursts of fear. The doctors blamed it on stress and terror and gave him medication that he had to take twice every week to calm himself down.
Unfortunately on Christmas day of 2005 he drank too much wine and completely forgot to take his pills, but at least he had fun playing games and eating Christmas food.
His fun, though, would not last as when midnight hit the next day he would hear distant breathing from his living room. Tiredly he stood up from his bed and grabbed a bat to fight the intruder to smithereens.
But instead of finding a robber or a maniac he saw a glowing purple bunny animatronic with red eyes and 4 rows of sharp teeth. Its ears seemed to be damaged and triangular, and inside of the animatronic he saw a human without any skin.
The being turned its head towards Williams in an unnatural and bone-breaking way. The one inside of the animatronic seemed to be crying and screaming in pain as it lunged at Williams.
Williams ran to the side just in time and tried to take the animatronic down with his bat, but it only damaged it slightly. Then it grabbed Williams by his leg and was about to chow down on it.
He kicked it in the face and pinned it to the ground with his other leg and screamed.
Mr. Williams
WHAT ARE YOU, YOU FREAK!?
Purple Bunny
I AM THE ONE YOU SAW DIE AND DIDN'T SAVE! NOW I WILL DEVOUR YOU!
The purple menace teleported out of Williams' grasp and pushed him on the ground. It ate his entire body, that is until he woke up in a hospital. No scratches or bite marks were on him which heavily confused him.
The doctors said that he had a heart attack and that he was very lucky that a neighbor was nearby to call for emergency services.
And they reminded him to take his pills as he nearly died from an illusion created by his own mind.
Til this day he never missed a single day without his pills until the doctors said that it was time to stop.
