Dream about my mother

My mom passed away in January after a long illness. I took care of her day and night in the hospital. She couldn’t speak in her final days, only nodded.

I have two regrets:

1.During her last days One night I scolded her out of stress when she kept calling me but didn’t speak. I still cry over it.

2. I feel I took her to the wrong hospital—maybe a better one could’ve helped.

I loved her more than anyone in my life

I just want one sign—a dream where she tells me she was happy with me, that I was a good son. That would give me peace.

Many people say they saw their loved ones in dreams, wearing white, smiling, looking young. Even a relative said she saw my mom like that. But I haven’t seen her in any dream.

I prayed deeply to Lord Krishna as I was attracted to him, chanted Krishna Vasudevaya mantra. But instead, I saw a Shivling in my dream. Since then, I’ve been chanting Saamb Sadashiv (as per Premanand Maharaj), but still no clear dream or sign.

Once I dreamed my mom came with me but was left behind somewhere.

I havent cleary seen her in dream

Instead I get random dreams

I don’t understand what it means. Any spiritual guidance? I still have tears in my eyes writing this.
