I had a dream in which there was a man named Sirius. What does Sirius mean?

It refers to Sirius. It is said that human ancestors were related to Sirius, and Angkor Wat in Cambodia was built according to Sirius. Because your dream description is unknown, you can't explain it accurately. You may be a sensitive person in life, sentimental, or in emotional entanglements, and you hope that the person you love can give you support.
