Last night i had a dream about this girl i have never met she seems familiar but i know 100% i have not ever seen her online or in reality before.

The dream started with me walking out of a club and down the street i cut threw a estate to get back home and there she was. Now i dont know what or who but a voice said to me walk her home. So i said to her do you mind if i walk you home and she replied ok. We walked for a bit till i said i dont mean to seem a bit wierd but whats your name. She replied Chloe. We got chatting and ended up going into a bar and drinking alot of Sambuca. (I know really strange dream). Anyway after that we walked threw a park still chatting not really sure what we was chatting about. We got to her house and i announced i dont actually live anywhere this area i live 22 miles away but i just wanted to get to know her and make sure she got home safely. She invited me in to stay the night since i was going to have to catch the train back and she said the area was dangerous at this time. So i went in and we just cuddled on the sofa then she pulled out a condom which had the top of the wrapper torn off. I pulled it out but it was dry and no use so we didnt have sex.

She and i are 18 in this dream by the way.

I know there is alot of detail in this dream but thats because it meant really quite alot to me at the time.
Anyone know why this may of happened? I have certainly never met or seen her before but i feel like im really close to her. I have dreams like this about once a month. So not very regularly
