If you dream of a gatekeeper or your personal security guards standing, it indicates that they are fulfilling their duties properly. However, if they are sitting, it may signal some discomfort or insecurity in your life. Such dreams often reflect the circumstances around you and your feelings of safety.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Keeper of the gate" (page 238).
If a notable or a public figure sees his keepers of the gates, or his personal guards standing-up in a dream, it means that they are performing their duty correctly. If they are sitting in the dream, it means that they are failing their duties. The governor's keeper of the gate in a dream represents glad tidings. Usually he represents a notable person, or a great person who is sought for advice, whereby both great and little people depend on him for access. The keeper of the gate in a dream also represents abeyance, or blocking one's access. (Also see Doorman)
Note: Islamic dream interpretation depends on the dreamer's circumstances and state. This is a general guide drawn directly from the source book.
