Floaters aren't noticeable all the time. When your eye is still or you are gazing into space, you may see them drift slowly across your vision. When you move your eye to look in different directions, floaters tend to move quickly. They don't follow your eye movement precisely and seem to dart away as you try to look at them.
Floaters may appear as dots, circles, lines, cobwebs or other shapes. They are usually grey and semi-transparent. Most floaters are small and quickly move out of your field of vision.
Here is a link to the British National Health Service websibe with an article on them.
They are not the same, but they may appear similar. Floaters are made up of broken down tissue. They tend to move with the eye, as you stated, and generally appear in the same area of vision, though they do "float."
Blue field entoptic phenomenon, on the other hand, is different in that all these lights follow squiggly paths across the eye--some paths run horizontal, some vertical, some diagonal. It really can come to look like a grid.
So, yeah, it could be floaters, but with floaters you usually only have one object in your vision--or more if you have more floaters, but they don't necessarily follow each other along paths; if you stopped moving your eyes they should settle. With blue field entoptic phenomenon, because it is actually white blood cells you are seeing, even if you don't move your eyes you will see pronounced movement as the cells follow one another along specific, squiggly paths along the surface of your eye.
The two do get confused much
