I would also like to point out that a large portion of the rest of the book Avkat Rochel (the whole work covers four volumes) is devoted to illustrating in niglah [revealed Torah] all the various points of these "signs" you say are from ambiguous Midrash [commentary]. Perhaps now you can better appreciate my reluctance to attempt to translate into English for you a couple of pages of the "signs".
To illustrate the point about incorrect expectations in context to the first redemption, after the plagues and even after the splitting of the sea and receiving mannah and water from the well of Miriam, almost the entire Jewish people believed from what they "saw" with their physical eyes, that they were in exile. This occurred at the time of the giving of the Torah. According to their "calculations", Moshe [Moses] was delayed. According to the commentaries around this section of Torah, the Soton caused the entire world to become dark and gloomy. The people became depressed and lost faith in the promise from HaShem [God] and Moshe [Moses]. It even states that the Soton showed the people the funeral bier of Moshe [Moses], meaning they saw his apparently lifeless body. As all the commentaries maintain, Moshe [Moses] was not "late" or delayed. The error was in Israel's expectation of what was supposed to occur.
As I am sure you are aware, the resurrection of the dead was also connected with this event except that it happened before Moshe [Moses] ascended Mount Sinai. In the final redemption, the order of events seems to be reversed.
A bit deep. Some explanation and tie-in's to current events later.
