This question is a bit odd. I have heard that when a person reaches jannah on day of judgement then they can ask Allah for whatever they want and their wish will be granted. Firstly does the level of jannah that you are on limit the amount of things you can ask for? And secondly I have been obsessed with fantasies like harry potter and pirates of the caribbean. Let's say I got to jannah and I asked Allah that I wanted to live a couple of years as the character Jack sparrow in the pirates of the caribbean movies. Will Allah Grant my wish and let me be Jack sparrow for about 50 years living in 17th century britain or does it not work like that? I was just wondering
I firmly believe that we can wish for anything in Jannah.
“…there will be there all that the souls could desire, all that their eyes could delight in: and ye shall abide therein (for aye).” (az-Zukhruf, 43/71).
“…therein shall ye have all that your souls shall desire; therein shall ye have all that ye ask for!” (Fussilat, 41/31).
“…what their souls desired, in that will they dwell.” (al-Anbiya,21/102).
Rest Allah Knows the best.
