This is a Brillant question! I hope this thread will pick up steam, its always fun to see something through the eyes of others.
It depends on the day and mood im in when i listen to an album or song because sometimes i can see different things.
I have seen myself interacting with the band in some songs like on Breakthru, like when Freddie and Debbie were doing their little duet deal.
Who Wants To Live Forever- Someone trying to call it off with their love because they have had much heartache and dont want to risk another. But in the end, they wind up together and it takes place on some majestic countryside or seaside.
Queen II- Total fantasy land of faries etc and humans in like a competely beautiful land. As well as with My Fairy King.
Teo Toriatte- I see Freddie/or someone as like a ghost figure in the backround singing to a lost loved one, (whether it be a break up or other means) as they remember him and their relationship. But it takes place in some majestic Japanese garden with water lilies and slowly flowing river at night under the stars.
When the night comes down- Brian is like explaining to someone his true nature, that there is more to him that meets the eye. That the way he is on the surface has different feelings from within. This also takes place at night under the stars, i always get a feeling of early fall time.
Liar- Freddie is pleading with God or an elder figure or perhaps a friend for forgiveness. And everytime he tries to apologize and act like hes turning another direction, the others chime in LIAR! with a flash of lightning as he is telling the lies. Then on the "Liar, Liar, Liar" section which Fred sings himself, hes saying an aside to himself that he is in fact lying. While he knows hes lying, hes pleading for forgiveness.
Among others, but ill be here forever. Ill add more later.
