You can project a 4D object onto a 3D space just like you can project a 3D object onto a 2D plane. If you use stereoscopic trickery you can for example watch a tesseract rotate on a phone screen. Don’t ask me how I know but if you spend an evening doing that sorta thing on shrooms 4D geometry might start feeling intuitive to you. Your physical senses are limited to three dimensions, your mind genuinely isn’t.
Imagine a 4D object if you think human imagination is limitless. Good luck
x ∈ ℝ⁴, there done
edit: if you want specifics, (1, 2, 3, 4)

ok, then imagine a 5D object
Ok I did. Im just built different.
