What happened to Jacque montrèal?

What really happened

Three years ago Jacque Montréal disappeared. He was a brother, friend, and all around great person . I don't really know what happened to him.
I woke up at three o clock in the morning to the loud sounds of waves hitting the pier. Normally I can sleep through it but today was different. I felt as if I heard screaming, as if somebody was scared for their life. For some context, I Iive on a clear-watered beach and we are the only ones who live there. The next house isn't too far away but it is a pretty fair distance. Anyways, I felt really uneasy, so I looked out the window to see what I thought was my brother screaming for help, yet when I ran out the house he was gone as If he was never there. No footprints. No, nothing. I didn't know exactly what to do, but I just figured that I was just hallucinating , because just a week ago they said they found my brothers rotten corpse. I didn't have anything else to do but just to go back to bed.
Another nightmare woke me up at ten o clock in the morning, I hate feeling like this. When I went downstairs I saw my mother eating breakfast I asked her where dad was and she said "he's busy at work like always".my dad was a forensic scientist, so that's why he was never really there after my brother died. However my mom, who was an actor, pretended as if everything was ok as if she wasn't in so much pain on the inside. She told me to take my seat so that I could eat breakfast. As I was eating breakfast, I felt as if I heard my brothers voice whispering in my ear saying "find out what happened", but when I turned around he wasn't there. I felt his breath on my ear but he wasn't there. Now I can understand me hallucinating, and I can  understand the nightmares, but I could feel him standing over me as if he was right behind me. I couldn't ask my mother because she's legally blind so I know she couldn't have seen what had happened. But I needed to know, this just didn't seem right.
Later that day, I went to my father's job to find out he wasn't there, I was really confused because my mother had just told me that he was at work. I asked his colleagues where he was and they said that he got fired five days ago. Now I was much more concerned and confused, I asked them do they know where I could find him. They said the same place he always is, the reason he got fired in the first place. I asked them where i could find him and they said Quincey library. Ok now I'm more confused, I asked them how could he be at that library if it has been closed since before I was born. They told me to figure out on my own because it wasn't their problem anymore saying as how my father was fired. So I told them thank you and went on to the library.
One hour later I finally found the library, when I went to the door I thought I was gonna find it locked, as the doors opened up they made a loud creaking sound. The lights were off so I was just thinking how could my father be here if there's no power. I called his name while walking through the place and my father grabbed me and brought me to this huge well lit room. I asked him how did he get power in this place seeing as the place was closed down. He told me "this is his secret hideout". I asked him for what. He said "I think I know what happened to Jacque". Then he just started typing on his computer, however I was getting really impatient. So I demanded him to tell me now because he was just murdered a few days ago. My dad said "Jacque was murdered however it wasn't by a person, it was a monster like entity". I told him that was genuinely crazy so I decided to leave. However, he stopped me and said "how could you think I'm crazy?, I bet you have also got the hallucinations and the whispering". I was astonished how did he know, I asked how did he know all that. He just said "didn't a voice like Jacque say find out what happened". I said yes, but that doesn't mean anything. He told me I know you could feel him standing there, breathing on you. He said "when I was in the bathroom while at work, I was rinsing off my face because of what the police said then I heard him whispering and i looked up and I saw this grotesque figure ,and after that day I just had to figure out what happened".
