Nightmares do ex friend keep coming up

So basically ever since this "ex friend" came into contact with me online and we spoke.
She bullied me a lot at school to put it simply bullied me at one at one school I had 6 weeks off and change schools. Following year she came to my school and unexpectedly we became friends.
Then when we went to study she bullied me along with this other friend that I had to change classes.

Following year I try to mend things but I wasn't "allowed" to sit next to them. At the time I didn't know how I felted or even could name my emotions before I went to therapy. However now I know I felt rejected,isolated and not good enough to be their friend. I was hurt and angry at them.

After studies which I left at that end of year, she came contact with me again back in 2011 and pretty much used me.
She said her father was pretty.mucn abusive and she stay with me at my mum's house. She never excatly hang out with me, always vanished at the weekends. It got too much I had to ask a friend to talk to her to leave.

So she did and never heard from her for a while.

Maybe 3 years later she contacted me again and we became friends..However I notice her and that other girl who bullied me at my art studies would hang out without me and I always felt left out and rejected.
Then when they included me in, it was okay for a while. But it all came to a head when I didn't want to go to this bush walk because of my anxiety. So my "friend" try to gaslight me and project blame on me about it and stopped talking to me..

The other friend was nice enough that she contacted me and told me she didn't want another repeat what happened at our studies.

However we fall out of friendship too.

The last time I had contact with that girl who bullied me from school and to studies, was back in 2017. I felted smaller and ashamed when she randmonly asked me when we were at the shops how much two or three schools bags cost together. I got it wrong and she said "Usally people get it right" I asked her later why she did that and her response was "I found it cute"
I spoke to the other friend before we fall out and told me how she use to pick on her with English because her English was her second language.

So after all of this she came back..
I thought to give it another try hoping maybe their be some closure. Maybe! she will recongise what she did to me at studies and apologies and we can heal together.
Well little did I know I would have flash backs of the past and have nightmares.
It's got to the point my therapist suggested to do EMDR therapy with me to help my brain to process the events because I haven't.

We have just started doing the "safe place" for EMDR therapy before getting to the memories..

At that time when I was talking to that friend she stopped talking to me all of a sudden. I feel rejected and worried I did something wrong. I show my therapist the message I sent to her and said it's fine what I said. It was just normal converstation.
I said to my therapist how I was suss because I deleted and blocked we will name them Jeff of my socail media. Because they were too part of the bullying and I kept having flash backs of them and what they did and say.
Because my "ex friend" is friends with Jeff may e he said something.

Though my therapist said if we check the facts there no soild evidence to prove this..
However I just think it's a strange conquences.
I have blocked and delete Jeff before but he came back after 6 months..My therapist told.me it's fine to talk to him just keep it minimal. I managed to get it to just send cat videos.

So that is the back ground. If you want it more in detail it is in my other forums.

Basically so 2 weeks ago I saw my "ex friend" in real life when driving by rescently. I live maybe 5 mins away where her parents live and she rescently came overseas. So....I'm always on edge of I will bump into her even walking my dog. I'm always high alert see a girl in the distance is that her!!??

Anyway

I've been having vidi nightmares of her and they aren't going away.

Does anyone have any advice how to get rid of these dreams?

Here are my two dreams as of this past week.

All names have been changed for the sake of their privacy.

I dream I was in my house and it was night time. My partner was by the main door and said "Ashely is here"
I said "I don't want to talk to her".
My partner told me "but she is sad".
So I walked to the main door. (Our door is made out of glass)
I stand their and saw her sitting down in the dark. I felt threaten or scared. As if I'm looking at some haunted ghost or monster, it looked like you could see her face.but it was also covered in darkness as well.
We spoke but all I felt was over whelming sadness .


2) I dream I was on the main road where I live.( It's called West Coast road, I use to get off from my school bus on that main street.
Anyway, my partner got angry at me because I kept mentioning about Ashely (Which is what been happening. He told me to block her because it's causing me too much distress. And Ashely hasn't replied since. I did post a picture of my bird wool felt but she didn't reply to that either. I did unfortanelty check her reddit and she was posting stuff which she was and as well post stuff on her Instagram account. So I assume she is ignoring me.)
In the dream my partner got so angry he threw a car on the grass patch next to the West Coast road.
The car went from big as he threw it, to a small toy car that landed on the grass.

Suddenly Ashely appeared in a black
Modern 1967 Chevy Impala car.
I had on the grass patch was a new duvet, a very old worn duvet and a black electrical blanket.
Ashely asked from her car "Can I have the duvet"? pointing to the good condition one. I responded "No"
and then Kate who appeared in the car as well asked if she could have my black electrical blanket. I remember specifically how her hand reached for it. I replied back and said "No, but you can have this one" which was the worn old duvet.
Ashely suddenly said to me "We are going to Keri Keri "(It's a hoilday town where I use to go in my teens with my family and family friends.) Ashely was about to drive off I heard Kate saying "Will Jeff be there"? and Ashely said "no"?. I did notice some other people in the backseat but they were in shadow so I couldn't tell.

I felt left out since they were going to Keri Keri and having a party.

I found out through a family friend that they didn't get in to the place were we use to stay because they drank too much.

And pretty much that was my dream..

Any Insights be much appericate it..

She isn't your friend.....friends don't treat one another like she treats you.
