Dealing with Kernel Panics
Disconnect any third-party peripherals including any USB hubs. Use safe mode to isolate issues with your Mac - Apple Support then boot the computer into Safe Mode. See Diagnosing problems- crash, freeze, panic, or spinning beach ball?, Don’t Panic! Understanding & Troubleshooting Kernel Panics in macOS, and How to fix kernel panics after installing OS X updates | MacIssues.
Kernel panics are indicative of possible hardware failure, so you should Check your Mac with hardware diagnostics or AHT. Read the kernel panic log: Mac OS X- How to log a kernel panic.
If you have no success figuring what is happening then you may need to examine the software you have running when the panics occur. Be sure it’s all current. If you must to resolve the problem erase the disk and reinstall macOS. Follow this outline to reset the computer to the factory-new state: Factory reset of your Mac - Apple Support.
You may be experiencing a GPU failure. Make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple. Also, see How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).

Try the following, and in the specified order, allowing enough time between each step to determine whether the problem is fixed or not.
Hey John!
I reset both the NVRAM and the SMC like you suggested. It's been 2 days now without crashes.
Thanks,
Vi
Update: it happened again. After about 1 week of working okay my iMac shut down while in sleep mode.

Thank you, John. I tried the first two steps. We'll see what happens.
Great! Thanks for the update.
I suppose you will have to proceed to Step 4. You will have to be patient while they have you repeat everything you already did.
I doubt Step 3 will help, but it won't hurt.
