1. Fire & Ice
a. In one sense, Fire was used as a symbolism to represent Sharanya's aggression / her imaginative & raging thoughts/ her inner fears / turmoils / getting burned
b. In another sense, it was used to represent humanness as in coldness getting burned up as in Shiv/ her image representation of coldness/being cold inside Sharanya/frozen nature is getting burned up with Fire & is a process of healing her. Frozen Nature / Icy Nature represents her Fears/ Inner Turmoil & shows how she is Frozen up with Feelings towards Vyom.
c. Also, when her thoughts are raging in fire, one hand of a image is consoling her & calming her down / giving her strength to heal / protecting her & she is getting confidence.
2. Water
a. When water was thrown into fire, the fire stops burning meaning that inner turmoil has stopped and that she is coming close to reality.
b. As her turmoil is going down, her image representation is cooling down & her image/ Shiv starts to smile/ happy. She is feeling happy and getting close to happiness.
Sharanya's comes to reality when Nawab starts barking to come inside her door.
