I can’t say for certain that this refers to your dream but this was my first impression and the #7 almost always refers to the spiritual.
This is from the book of Revelation Chapter 17 and refers to a vision the apostle John had of a prostitute riding a beast with seven heads and ten horns:
9“This calls for a mind with wisdom. The seven heads are seven hills on which the woman sits. 10 They are also seven kings. Five have fallen, one is, the other has not yet come; but when he does come, he must remain for a little while. 11 The beast who once was, and now is not, is an eighth king. He belongs to the seven and is going to his destruction.”
Some scholars have said that the 8th king is not a king at all but refers to a system-maybe the internet, which may be the numbers you saw displacing the kings…but it doesn’t look good for him(it,beast) either in the long run. :)
Regardless it’s worth a read.
