Final answer:
The old fortuneteller finds Santiago's dream difficult to interpret, which makes him suspicious of her.
Step-by-step explanation:
The old fortuneteller, also known as the Gypsy, says that Santiago's dream is difficult to interpret because it contains symbols and signs that are complex and require deep understanding to decipher. Dreams can often be ambiguous and hold multiple meanings, making them challenging to interpret accurately.
Santiago is suspicious of the Gypsy because she is not forthcoming with a clear explanation of his dream. He feels that she is withholding information and doubts her ability to truly interpret his dream. He wants a straightforward answer and is skeptical of her vague response.
