How can I make a “vertical dotfill” environment?

Wanting to highlight parts of my text, intended to be read at second reading, by an inexpensive method in packages, I want to set up an environment that would put points at the beginning and end of the line, preferably at the margins of the environment. I obviously want to be able to include in this environment to create all kinds of texts or mathematical objects, like figures, theorems, footnotes ... I give an example of what I want to create, which I made by adding dotfill, at the beginning and at the end of the text, while adding points at the beginning and end of the line thanks to hfill. I actually want to create a, say vdotfilltext, environment, based on the idea of the dotvfill command, included in the answer to the following question vertical dotfill and then put my text between dotfill up and down, and between some vdotfill between right and left. Any ideas
