To dawn (up)on (someone)
To occur to someone, especially very suddenly or unexpectedly.
🌀Once I pulled up to the bank, it dawned on me that I had forgotten my wallet.
🌀Did it just dawn on you that throwing the ball in the house might be a bad idea, or did you have that realization before breaking mom's vase?
🌀Then it dawned upon me that I was actually going to have the job.
🌀On the way home, it dawned on me that I had never returned your call, so when I got home I called immediately.
