where do I start

Okay less just go from the first night I became David the one above all I was going through so shit to be honest I just got kicked out of my house so I'm living with my older sister and for at least a week weird things where happing like how my sister would just be crawling on the floor until I saw her and said what the fuck are you doing and she would just reply with oh I was gonna scare you which is probably true so I just nudge it off but one night I saw a white dog with like it's body was cracked like waves like scales and a long tail at the end of my bed and the only reason I saw it was because I looked into the glass door just on the other side of my room to see it crawling next to me and it got a lot worse trust me it got a lot worse from then and now I'm still in belief I might be gifted or iv done some sort of black magic or my family is keeping me hostage in hell with dreams and more dreams like an infinite loop of different words but all the same Because some times I would bring up a subject only my fiends would known only to have them say what that never happened even tho it was legit the day before it happpend so I'm starting to believe I'm stuck on the earth or some sort of black curse or dream I made when I tried suicide or even when I got to high just something doesn't seem normal about I guess
