In one of my favorite books, The Lion, the Witch and the Wardrobe, two older siblings (out of 4) are worried about their younger two siblings. The youngest is claiming that the next oldest was with her in what sounds like an imaginary place. The wise professor asks the older two which sibling is the most likely to tell the truth-and then tells them to believe her even though her story is hard to believe.

From what you have written here, your t sounds like she tells the truth. If you know her to be truthful, then she is probably telling the truth.
