Elephant memory

This spell is more so illusion based! So it basically goes inside the targets mind and digs around and takes a traumatic memory  that keeps you up at night

When casted the target must make Constitution saving throw of 16, if failed they immediately take 1d4 nerotic damage.  From there the spell takes effect and you relive this moment over and over again, at the start of your turn you take 2d4 damage and every round you add 1d4! You must make a Constitution throw inorder to break it! You are under the petrified effect and also have disadvantages on all attack and damage rolls!
