Do you have an internal monologue? … a voice (your voice) that can say things in your head?

It seems some people can imagine some subset of: visuals, audio, smell, sensations (falling, acceleration) easily… and sometimes it takes people a lot of effort.

I take pauses, a few seconds, after reading a description of a person, event, place etc to build a mental picture and continue reading with that in my head. Once created, my head maintains it as I read on.

If you can’t yet, start with something simple… an ambiance of just a color, a time of day, the smell of soil etc.
