Dreamt of tying oneself with a vine after Istikarah

Assalamuallaykum Warahmatullahi Wabarakatuh we have an online business that my mother did Istikarah to know whether its best to move forward by promoting it and if yes, on what platform it is best to promote it on and she gave 2 different platforms as the options in her Dua. She prayed Salaat-Ul-Istikarah for and had a dream on the 4th night. She dreamt that she was sitting comfortably on a open space on a big grassland. Her mother in law was standing there, my mum then got up and walked off and her mother in law sat on her place. My mum then found herself sitting on a very small place at the front which looked like a airplane and it started moving and she became very scared thinking the plane may hit the trees that were there. She didn’t crash into anything instead she then found herself in a open space that was able to move she then tied her right thigh with a vine which had no leaves on them and she said she was ready to someone she felt was there but couldn’t see. When she woke up she was upset. Please can you tell us what this means and provide us with the best advice.
Jazakallah
