This was rendered with Eevee and Blender 2.9.
The wall to the back right room does touch the floor (actually it extends behind the floor and pokes through it). That back room has a Spot Light lamp in it along with a animated char which is being reflected in the main rooms floor.
The first clip was imported to Davinci Resolve to add the red circle and and weird stuff happened to the image quality, but i still wanted to post it with the red circle to point out the reflection. The second clip was the render from Blender.
Thanks again @lehuan5062
For the scene im using Screen Space Reflections in the Render tab, it was also enabled in the Materials Settings for the room texture(s) which was causing the issue. Dont know why this is the case (anyone with an explanation here would be great), but by un-checking it in the Materials Settings the issue when away and the walls are now being reflective and not the objects behind them.
