Will history repeat itself again? Drop to the line?

I'm not a financial advisor, take anything said with a grain of salt. I just like looking at charts and spotting any kind of patterns I notice.
This looks very similar to the previous bear market where it went under the line, then went sideways for a bit, then had a steep drop!
When it dropped, it dropped hard and fast to the line again, then proceeded to run sideways for a bit before going up again.
What goes up, must come down, be safe out there!
