Daedalus Syncing Blocks - after PC restart


Hello, is it normal for Daedalus to sync blocks after the computer has been restarted and or shutdown overnight? The wallet was up and running fine. I was receiving money fine, but when I restarted my computer and clicked on Daedalus icon on the desktop to open my wallet, it is doing what it was doing when I first installed it, it is Syncing Blocks again, starting at 1% and working it’s way back to 100%. Is this normal? What about the coins I have in it? Are they safe and secure? Anything I should be worried about? Thank you!
