Food for derision and mirth.
No passage of scripture is subject to private interpretation. ONLY the Bible interprets the Bible. Every symbol in Revelation is explained somewhere else in the Bible.
If you would actually like to know what the meaning of what has been foretold ... here is a good beginning.

Sorry, no one can know with absolute certainty what Daniel is referring to. Even Daniel did not understand all that he had seen, and he said so. There were things Daniel saw that he was commanded to not reveal.
Even the source you linked was weak in its arguments about Chapter 7.
And the linkage we were discussing was Rev. 12 and Daniel 2, not Daniel 2 and 8 and Rev 13, then with 7, a sequence which your source discusses at length.
I’m well familiar with various end times theories and views.
But it is abundantly clear that God gives us enough information, so that when we are in the events being described, we will recognize them. Not one jot or tittle will be overlooked or dispensed with.
But as for knowing all of the eschatological details, there is room for interpretation.
In the end, it will unfold as God has foretold, whether we understand all of the symbolism or not.
