Charles Ellicott Commentary Zechariah 4:1

"And the angel that talked with me came again, and waked me, as a man that is wakened out of his sleep." — Zechariah 4:1 (ASV)

Came again, and waked. —Better, possibly, again waked me, the construction being similar to that of Zechariah 5:1. But it is not impossible that the angel had gone out, as before (Zechariah 2:3), to receive some fresh instruction from a higher angel, or from God, and that he now came back again.

From this verse it would appear that between some of the visions the prophet fell into a state of lethargy, and that the angel roused him; or it may be that all the visions were seen in a dream, and that he only seemed in his dream to be awakened. (See Note on Zechariah 1:8.)
