Glitch:
When entered with a follower, the screen goes black, with some psychedelic colours along what used to be the walls of the barrow.


Likely cause (game's scripting/coding issue):

Workaround:
Telling your follower to "Wait here" before entering the barrow is enough.

Thank you so much, that was driving me nuts, I wasn't sure if it was meant to do that so casting light and so forth but also lost the tab ability in there to load any items or spells.

Thanks for this workaround. I even posted a topic on this about a week ago, but nobody came up with a solution.

What had worked for me before is quicksaving/quickloading inside the cave, but your's is better. =)

Unfortunately that solution did not work for me I told my companion to wait outside but it still had the dark/blurry graphics and inaccessible "Load" option in the menu.
