So I'm gonna do a Supernatural/Doctor Who imagine, where Dean is the doctor and you fall for him. My friend got me on to Doctor who. So enjoy and imagine Dean has a British accent or if you want, you can imagine it's just his regular voice
It was a cold, Autumn day. You were in your apartment, you got up, took a shower, dried your hair, got dressed, did your make up and you grab your bag because you had school. You did not like school, the other kids were just mean to you and you didn't like your teachers. One day you were heading to school and then you bump into a guy, with beautiful green eyes, short brown hair. He had a leather jacket, a cool looking medallion and looked about 27.
Dean: excuse me. sorry for crashing into you.
You: no, no it's fine. I should of been paying attention. Who are you?
Dean: I'm Dean, but a lot of people call me doctor.
You: why?
Dean: I'll show you why.
Dean grabs your hand and he runs to his tardis. You see a blue box, that says police box above the door and there was light at the very top of it.
You: what is this?
Dean: it's my tardis. It can camouflage into anything, but my favourite camo is this.
Dean makes it turn into the impala.
You: did you just turn that into that?
Dean: *smiles* yep. the blue box is my space machine.
You: space machine?
Dean: yep. it can travel through time and it can make me go either forward in time or backward in time. But I needed to camouflage it and I needed to find you, y/n.
You look at Dean.
You: how do you know my name?
Dean: it says on your bracelet. *points to your bracelet*
You: oh.
Dean: what does it say?
You: it says "my dear baby sister y/n, I love you so much. Wear the bracelet forever and always. Love your brother Sam."
Dean: What happened to him?
You: he was killed by a drunk driver.
Dean: What about your parents?
You: they weren't really loving parents. they didn't like me or Sam and one say Sam took me away and we lived together and ever since he died, I've been all alone.
Dean then hugs you tight.
Dean: if you want you can come with me.
You: really?
Dean:*smiles* really. go pack a bag.
You and Dean drive to your apartment and you pack all your clothes, Dean was looking through your brother's clothes.
You see Dean looking at your brother's clothes.
You: if you want you can take some of his clothes.
Dean looks at you.
Dean: I don't think they would... *holds one of Sam's hoodies* fit.
You: my brother was tall.
Dean: it looks like he was. How tall was your brother exactly?
You: like 6' foot something. my friend Crowley, called him Moose.
Dean: Moose?
You: Yeah because my brother, some how resembled a moose to him.
Dean laughs at what you said and you bring everything you owned. You and Dean were packing the "impala" and you gave the landlord your apartment key back and he smiles at you and everyone in the building where you and your brother lived, watched you and Dean drive off. Dean drives to a alley way, he then makes the car turn back into the tardis and then he unlocks the door and he grabs your hand and he shows you the inside of the tardis.
You were amazed by the size of it, from the outside it looked smaller, but the inside, it was very spacious.
You: this is your tardis?
Dean: yep! it's my time machine. So where would you like to go? Backward or forward?
You: i don't know.
Dean then begins making then tardis work so it can go through time.
Dean: do you want to go forward in time?
You: I'd love to. *smiles*'
Dean was getting the tardis to work and then it started making it's sounds like for when it's about to go through time.
Dean then runs to you and he grabs your hand and holds it tight.
Dean: here we go!
You didn't feel the tardis moving at all, then you smile at Dean and he smiles at you.
Dean: my god your beautiful.
You blush.
You: y...you think I'm beautiful?
Dean: yes. *smiles* y/n I need to tell you why I can to your time.
You: why?
Dean: I knew your brother, sam.
You: you knew my brother? but he never spoke about you.
Dean: I know. I asked him not to talk about me. and he wasn't killed by a drunk driver.
You: who killed him then?
Dean: he was killed by alien. We were fighting a few of them a few month ago and then they attacked him and they killed him.
You: but when the police came by, they said he was killed by a drunk driver. I don't understand.
Dean: the aliens made it look like he was killed by a drunk driver and then... wait did you say a police officer told about your brother's death?
You: yeah why?
Dean: that was one of the aliens.
You: but it looked like a normal police officer but after I closes the door there was this bright blue light.
Dean: y/n?
You: yea?
Dean: I think the aliens are coming after you now.
You: but what did I do?
Dean: I don't know.
You and Dean arrive to the future and you see the future.
You: what happened?
Dean: a very horrible war.
You: a war? between who?
Dean: all of the things in the universe. I was in it and I couldn't help a lot of aliens and they hated me ever since. I'm surprised you don't hate me...
You then run into Dean's arms and you hug him tight. Dean then wraps his arms around you and he holds you tight.
Alien: well, well, well if it isn't dean.
Dean looks up and you look up and you see a alien.
Alien: I see you brought us our desert.
Dean holds you closer to him and he holds you tighter.
Dean: she's not for you.
Alien: aw, but she looks yummy. Like her brother.
You: what did you say?
Alien: we killed your brother and he was screaming and he yelled for your name.
You were starting to get angry and you grab Dean's sonic screw driver and you then use it, but the aliens laugh at you, then you made something explode and the aliens started shrieking.
You and Dean run back to the tardis and then the aliens begin chasing you guys.
You: DEAN I'M SORRY!
Dean: WE CAN TALK ABOUT IT LATER! LETS LIVE FIRST!
You and Dean arrive back to the tardis and you both get inside and Dean locks it.
You: let's get going!
Dean: no. we need to destroy those aliens.
You: but how?
Dean: they hated the explosion you created.
You: so you want me to...
Dean: make this place explode like a firework.
You: won't I get killed?
Dean: no, I'll be with you.
You: but we'll both die.
Dean then kisses you. You both then pull away.
You: what was that for?
Dean: I was trying to make you shut up.
You laugh, then you and Dean go destroy the aliens and then you both head back to the tardis.
You: we did it Dean! We killed those aliens!
Dean was walking toward you and you were walking backward.
You: Dean I'm sorry for making the explosion before.
Dean was quiet and then you walk into a wall. Dean then pushes you closer to the wall.
You: Dean?
Dean then kisses you again. He puts his hands around your waist and you put your arms around his neck.
Dean: I love you y/n.
You: I love you too Dean.
Dean: stay with me.
You: what?
Dean: stay with me. travel through time and space with me.
You: okay. *smiles* I'll stay.
Dean smiles at you and you both kiss each other again then you both fall onto the floor and then you both make love in the tardis.
