What research shows
Not measured. Colour salience in dreams is low overall; rainbows are the exception that gets recalled.
Nature and elements
Dreaming about a rainbow
Dreaming about a rainbow is traditionally read as something beautiful and untouchable at once — the rainbow is the only dream object that recedes as you approach. No survey has measured how often this one occurs, so we give the reading without a frequency — only 19 of the dream themes here have a published figure at all.
The psychological reading
A rainbow has no physical location — it exists relative to the observer, so two people never see the same one. Dream reports rarely include anyone else seeing it.
When it turns up
Why this dream arrives when it does
A rainbow is the only dream object that recedes as you approach it, because that is what real rainbows do — they are an optical effect positioned relative to the observer. These dreams arrive around beauty or hope that cannot be possessed.

The version matters
Different ways this dream shows up
The version carries most of the information.
Reported almost exclusively in pleasant dreams, and often at the end of one, which fits the resolution reading.
A rainbow after rain
The classic sequence, and it is reported after difficulty rather than during it.
Chasing the end of one
The folklore promises gold and the physics guarantees failure. It reads as pursuing something that moves as you move.
A double rainbow
A searched variant, and real: the second arc is fainter with reversed colours. Dreamers report it as significant without being able to say why.
A rainbow indoors or somewhere impossible
Dream physics. It usually reads as something good appearing where it does not belong.
A fading rainbow
Brevity noticed. It follows good moments that have already passed.
Walking on one
Fairy-tale imagery, and reported as joyful. It clusters in childhood memories.
Commonly claimed, and wrong
What this dream does not mean
Rainbow dreams are not promises, and the pot of gold is a folk tale. The biblical rainbow is a covenant rather than a forecast, which is a different claim again and belongs to belief.

Questions about this dream
What does it mean to dream about a rainbow?
Usually something good that cannot be held on to. It is typically reported after difficulty rather than before.
What does a double rainbow mean?
Dreamers report it as weighty. Physically it is a second reflection, and no meaning attaches to it beyond the impression.
Is it a good omen?
It is a pleasant image rather than a forecast. Nothing in a dream predicts events.
