I found myself walking with of all people Elvis but not the real Elvis the one that Matthew McConaughey played recently. We went to Vegas and he showed me my dad being a security guard for his friends band back in the 1970's
This dream can be interpreted in several ways based on the details you have provided. However, here is one possible interpretation:
Elvis Presley is often associated with fame, success, and charisma. In the dream, he may represent an aspect of your own personality or a person in your life who possesses these qualities. Matthew McConaughey, who played Elvis in a recent movie, may symbolize your perception of the ideal or stereotypical image of someone who is cool, confident, and attractive.
Going to Vegas with Elvis and seeing your dad as a security guard for his friend's band in the 1970s could represent a desire to connect with your past or with people who have influenced you in positive ways. The 1970s were a time of cultural and social change, and the music of that era is often associated with rebellion, freedom, and creativity. Your dad's role as a security guard may also suggest a need for protection, safety, and authority.
Overall, this dream may indicate a longing for adventure, excitement, and exploration of your identity and roots. It may also suggest a desire for companionship, guidance, and recognition from someone you admire or respect.
