Hello~
I have been having nightmares recently again and I feel bothered by it. I dreamt about my sister (whom we had an argument 1 year plus ago) and till then we haven’t been talking.
It was very heavy for me to process with the words that she had said to me despite me helping her bringing her to overseas but it felt like argument made me see another side of her. My previous therapist suggest me to write a letter to her as a closure for myself which i did in march. No reaction or response from her which i have expected.
I know this can’t be force and I did whatever I can. However she has blocked me on all platforms. And told me in face that she gossip about me with her friends. I admitted i start with blocking her on ig however after reflecting I felt i should not do this.
I been seeing therapist and my sister argument and my previous relationship caused huge trauma to me. My dreams i kept dreaming that she said nasty words etc and fellow friends does my dream meant that i have unsolved feelings? Or also how can i stop having these bad dreams?
Dear @reassuredturnip9
Thank you for reaching out. I can see that you are going through a painful experience with your sister. I believe it hurts because you care for her deeply and have been trying your best to mend things. Understandably hurtful words, blocking, and lack of closure have left a deep emotional impact, which is affecting you in the present.
I think your dreams may be an indicator that your mind is still processing unresolved hurt, regret and trauma. Even though you logically know seeking reconciliation require mutual commitment, emotionally there is lingering sadness, grief, and deep longing for her.
I am glad that you have been seeing a therapist and even wrote the letter to your sister for your own closure. That already shows you are trying to heal in a healthy way. I recommend to discuss these dreams in therapy because trauma and emotional stress can sometimes show up through recurring nightmares.
May I check if there a family member who you both trust and respect and who is willing to intervene and mediate between your sis and you?
Healing from family wounds takes time and patience. Identify your own values and let your future decisions and actions be guided by them amidst the challenges. Be clear on your own boundaries, and this can protect you from getting hurt or causing hurt. Most of all, be compassionate to yourself. 
Hi CaringBee
Thank u for replying to me. My mom has reach out as the middle person to meditate but it aggravate even more. My sister is the type that the more you push her to do it the more rebellious she is.
I will discuss more with my therapist on this on how we can work through. Also it’s only the start of it so i am not sure how long is good enough for me to see if this therapist is a good fit for me.
