Why am I getting random lights on the bottom of my scene?

I am working on an Udemy course, and lately I am getting random red lights on the bottom border of my viewport. It will go from a couple of lights, to a large number (as seen in the image), to even the whole scene being light as if there is a red light source below the camera. Has anyone encountered this and/or know what is wrong?

It goes away I leave maximized mode if it occurs while the editor is maximized, or vice versa, if I maximize the editor from normal mode when it occurs in normal mode.
