I was watching Blue Velvet last night and there is a scene I believe where Jeffrey is at work and at the edge of the shot is a lamp with a gnarled tree like base and red shade. Unable to check this at the moment and wanted to post this before I forgot. Has this been observed or discussed? Dorothy Vallens is also billed at the Slow Club as The Blue Lady. The Slow Club also seems to share the same vibe as Club Silencio.

The cars parked outside, drawn once again to the red car that was racing alongside the white car.
(update)
The lamp is at 53:43 on the dvd. It is in Jeffreys home. Gnarled tree base and red lamp shade.
