To dream that you spy upon others through a keyhole, you will damage some person by disclosing confidence. If you catch others peeping through a keyhole, you will have false friends delving into your private matters to advance themselves over you. To dream that you cannot find the keyhole, you will unconsciously injure a friend.
A keyhole can symbolize our tentative entry into the Sublime or transcendent state. Our vision is somewhat restricted and even in dreams we do not yet have confidence to remain in that state, but must accept the need to remain grounded. Since a key usually requires a keyhole, to dream of one without the other indicates some kind of confusion between the inner and outer self. A keyhole by itself can represent gossip or treachery by a close associate. When we dream that we are peering through a keyhole, we are conscious of the fact that our ability to see and understand is somehow impaired. Conventionally, the keyhole has been taken to represent the feminine, so that impairment could result from our attitude to the feminine and to feminine qualities such as intuition. When a woman dreams of a keyhole without the key she will be conscious of her own vulnerability. In a man's dream he will need to look at the sensitivities of people around him. Not being able to find the keyhole suggests he has not yet quite understood those sensitivities either in personal or work relationships. You might also like to consult the entries for Key and Lock.
It can mean that you are close to a solution or before you the new direction in life, but not absolutely there and when you expect it has to open. Whether you think of new opportunities to dart a glance at a situation or the person on the other hand?
You are close to a solution, or in your life there has to be a new direction, but not at once. Return to a dream and present that you have a key from this door and that you open it. It very much will help with real life
Peeking through a keyhole or other opening can mean:
You are curious about something or want to learn the truth about it
You are curious about a certain person, or possibly even suspicious of their motives
You feel like exploring new areas or learning new things
You're mind is on what might be coming next in your life, when you "walk through the door" into the next phase of your life
