Update: He is still saying all this stuff

My mother got a call around 12ish at night from my older brothers girlfriend, she said he'd went out somewhere on his own without notice and hasent been back for a while. My mom went out looking for him, i decided to call him myself as he would answer my phone call and not my parents. I asked him, where he was and if he was safe, My call ended up making him want to come home. My mother tried talking to him, asking what is it she can do to help and just why he would do this to her.(he scared her cause she thought he might've been trying to do something stupid.) Obviously he still wasent making sense, talking about "Having the world in his hand." While pointing at his phone, saying me and my little brother are the future, saying he had lost faith or my mom or dad had lost faith in god, saying he sees the future and yeah all this stuff. He made my mom cry cause he wouldn't listen to her, she asked him to please try to at least get some rest as supposedly he had not been eating or sleeping right...but he wasent having it. I ended up switching places with my mom, he was more calm and comfortable talking to me and such cause I listen to his rambles. Took a good while before he actually decided to try sleeping, as before all he did was talk about his phone and the "power" it has. The "Power" it has over him and "power" it has to "make stuff happen" also at one point he gave me his phone, telling me to "Go put it in the kitchen" as it made him feel uncomfortable, and that it was listening, one point he even suggested going out and smashing the phone himself.

He ended going to the bathroom at one point, so I hid his phone...as I felt it was 1.) The only way to keep him here, and 2.) He always glued to it when he should by trying to rest.

Extra update: He came back and finally decided to go back to work, i think his girlfriend had a good chat with him. He's still kinda talking like a weirdo crazy person though...but hopefully he'll be alright.
