Grey Glove in dreams
A covering for the hand — protection or formality placed between you and what you touch.
How grey changes the reading
Grey colour layers ambiguity onto the symbol. The base meaning is still there, but the dream is saying you do not yet have the colour information — the situation has not declared itself.
The base reading of Glove
A glove in a dream is the dream's image of a chosen layer between your hand and the world. Gloves keep you warm, keep you clean, or signal that the work is formal enough to require them. The dream brings the glove when the question of how directly you are handling something is alive — are you touching the situation bare-handed, or through a layer? A glove that fits and does its job is the dream telling you the distance is correct. A single lost glove is the dream noting that one side of you is exposed where it should not be, and the matched pair has been broken.
