But her dream is very post-trib so that doesn't make sense. Read this:
Dave MacPherson wrote a book that blamed Margaret McDonald for starting the pre-trib doctrine. In the book he presented Margaret’s vision, except he removed two parts of it. The two removed sentences were, "
This is the fiery trial which is to try us. - It will be for the purging and purifying of the real members of the body of Jesus" and "
The trial of the Church is from Antichrist. It is by being filled with the Spirit that we shall be kept". Obviously her vision is post-trib with the antichrist persecuting the Church.

“The first problem with the MacDonald origin is the fact that she wasn't the one who widely taught the doctrine of the pre-trib rapture. A man named John Darby is believed by many to have sparked modern interest in the rapture. The question here is how Darby came to hear of MacDonald's vision. Proponents like Dave MacPherson and John L. Bray have never been able to prove that Darby had ever heard of MacDonald or her vision.
Darby himself claims the revelation of the rapture came to him when he realized the distinction between Israel and the church.
Darby reported that he discovered the rapture teaching in 1827, three years before MacDonald had her vision.”
