Who am I •Chilling Adventures of Sabrina

Where am I?

I eventually arrive at my friends place and knock on the door. She answers "Oh hi, Ash" "Hi, Jane" "lemme just get my shoes on then we will head to, whatever this place is" I nod and wait. She eventually exits the house and and we start to walk. I say "it's about a 10 minute walk from here. But I promise you, you will not regret it" we both chuckle a bit and just talk about casual Teenage stuff.
We get to the block that the place is on, "Woah, Ash. How did you even like find this area?" "I don't know, I was just kind of.. scrolling through the internet and it said come check this place out." She nods slightly. We final arrive there and say Woah at the same time. It was, different from what I expected. It has some writing that says "Gehenna Station" and it pretty much looks like a building from the late 1900's. I start to walk up to up close to the door and Jane just kind of wanders around curiously not paying any attention to me. I say to Jane "See, I was right. You wouldnt regret it" "Yeah, I guess you are right. Hey, try knocking on the door." Then she giggles, as the teenager I am I say to her "Bet" then I gulp and say to her "if anything happens to me, just walk back to your place like nothing happened and tell my parents nothing." "Ok, whatever" I then knock on the door and Jane for some reason  backs up even though she is nowhere near the door. The door rattles a but and then moments later I am gone. Jane says "haha, very funny, Ash.... Ash? Ok, you can stop now" she then hyperventilates and then remembers what I said "if anything happens to me, just walk back to your place like nothing happened, and tell my parents nothing". She does exactly that, she walks down the street looking like nothing happened. I come back and see Jane is already gone, I dont remember anything of what just happened. I see this Woman next to the open door, she says "Who are you and what do you want?" She has this strange, almost Australian accent, and I say "I-I came here with my friend to check this place out. And I dont remember what happened and now I am here and she is gone" The woman replies with "that doesn't answer any you specifically came to this place" I sigh then say "My parents. They used to go to this school. But never told me about it, so I wanted to come check it out for myself. To see if it was real" She looks at me with confusion, "So, you are a Witch?" "Yes, Ma'am" "Well, you can come on in, and you can tell us more about your Family" I nod and she holds the door open for me to enter, as I enter she says, "You can call me Ms. Spellman."
