No you’re not going crazy (any more than usual).

You’ll be looking at that clock an extra few times today thinking it’s wrong.
You’re just dealing with the time change…and darkness in the afternoon.

The time of year when in bed, you close your eyes for 10 minutes at 6am it’s suddenly 7:45AM.
At work when you close your eyes for 10 minutes at 1:30pm, open them: it’s 1:31pm.
