Hi Vidyun ,
[ Commenting after viewing your portal series of images. You might find this unrelated and even off theme to your idea of portal as you used for the set of images here . So, discard my comment if necessary ]
Portal as an allegorical concept in philosophy and architecture etc. has existed for a while now. Interestingly it was sometimes seen as an escape , a window to the otherworldly . Sometimes a place to be aspired for but hard to attain and other times a dangerous parallel.
Felt this was related to your expression in these set of images even though it was not exactly same.
This video explains some of the points that came to my mind after seeing your images . The person speaking is Eric Weinstein who is a physicist and an economist . He hosts a podcast by name The Portal.
