My Dad gets angry with me about everyday. Any advice?

The anger can last for a short time or 4 or 5 hours, might extend into the next day. During a home improvement installation the installer told my dad and me how long, who else was involved in completing the task and about how long. He misunderstood, but when I tried to explain where he got confused I was accused of taking control away from him. He comes in my room when I stay with him and turns on the light while I am sleeping to see who's there and if he has someone to feed. I've been dealing with this for 2 1/2 years. thank you vlg
