I am looking for an informal idiom or expression to imply that my brain has stopped working temporarily because say I have dealt with a heavy math question or I have gone through an overwhelming process or I have run across an astounding view etc.
When your phone crashes or acts up frequently and operates with delay, you can simply say:
- My cellphone keeps freezing.
I was wondering weather we can say:
- My brain has frozen.
Once I have heard:
I've got a brain freeze.
But I couldn't find any web source to back it up. Please let me know about it any any more fitting and natural idiom or expression.
