Yes, sometimes it is like watching a movie.
I have learned a few things to try to do if you can be cognitive while in them.

For instance, try to look at your feet, your clothes to see what you are wearing, helps to date the timeline.

Some visions are like watching someone's else's time and some are more like you are the one doing the action.

In Nana's visions the frames go by fast and I cant seem to go back to any of them later, so I try to look around in each frame to see as much detail about where I am seeing in each one.
Afterwards I try to verbally record them or write them down as i will forget them or parts of them within a few seconds sometimes.

Some are more like remote viewing something happening now, in the future or in the past. Looking around at the surrounds to take note as much as possible helps to determine which one you are in.
