If we consider a hypothetically possible situation, then the bitcoin's fall below "the peak price of the previous halvening cycle" will mean that something unusual and force majeure is happening, which means that need to start to get nervous and panic?

This is not excluded, but as NotATether claims above, the probability of this is minimal, because until now, this has not happened. So, most likely, the price will hang around at this level and will not go lower.
