A lamp in a dream

Aisha used to sleep stretched out in front of the Prophet ﷺ while he prayed, and she adds, almost as an aside, that in those days there were no lamps in the houses (Bukhari 513). The Prophet's own household slept in the dark. Yet the Qur'an's best-known picture of light is a lamp.

That gap is the shape of this entry. In the sources a lamp is a bigger image than any object on a shelf, and the dream readings sit on top of it.

A lamp in glass, in a niche

The longest picture of a lamp in the Qur'an is a parable. The likeness of Allah's light is a niche, with a lamp in it, the lamp in glass, the glass "as if it were a pearly star", lit from a blessed olive tree "neither of the east nor of the west", whose oil would almost glow untouched by fire. "Light upon light", and Allah guides to His light whom He wills (Qur'an 24:35). Notice what the verse does and does not do. It says what the whole picture stands for, which is His light and His guidance. It does not hand out meanings for the niche, the glass or the tree, and the commentators have not agreed on how to do so. We will not choose for them.

Two other Arabic words complete the Qur'an's picture. The word in that verse is مصباح, a household lamp. The plural of that word is what the Arabic of Qur'an 67:5 uses for the stars that beautify the nearest heaven. A second word, سراج, is used for the Prophet ﷺ as "an illuminating lamp" (Qur'an 33:46), and for the sun (Qur'an 71:16). So in the Book a lamp is whatever gives light by Allah's appointing, whether a sun, a messenger or a star. That fits the way dream lists reach for guidance first.

The lamps the Prophet explained, and the one he said to put out

The clearest explanation we found in the Sunnah of lamp-like lights is not about a dream. Usaid ibn Hudair was reciting Surat al-Baqara by night, and his horse kept shying whenever he read. When he looked up he saw something like a cloud with what looked like lamps in it, and it went up out of sight. The next morning the Prophet ﷺ told him they were angels who had drawn near to his voice, and that had he gone on until dawn, people would have seen them, for they would not have vanished (Bukhari 5018).

That is a waking sight, and we cite it as an interpretation of lamp-like lights, not of a dream. Yet it shows the Sunnah's most direct link for the image: light that comes near when the Qur'an is recited. In another report, two Companions leave the Prophet's company on a dark night and find two lights like lamps going before them (Bukhari 465).

The same Sunnah has a plain, practical rule for the lamp in your room. Put out the lamps when you go to bed (Bukhari 5624). Another report gives the same instruction, with a reason for the vessels and doors that go with it: Shaytan does not loosen a waterskin, open a door or uncover a vessel (Muslim 2012a). A dream lamp, whatever else it is, burns in the one place where the Sunnah says to put every real one out.

What the lists read from a flame

Popular dictionary lists read a lit lamp first as knowledge and guidance, and that follows the Qur'an's use. They read it second as a person: a scholar, a guide, sometimes a child. A lamp lit from another's, they say, is learning received. The state of the flame stands for the state of the guidance, steady or fading. This is reasoning from the Qur'an's own imagery, and the step from "the Qur'an uses a lamp for guidance" to "a dream lamp is guidance" is the compilers', not a text's.

A lamp is more than a flame

Modern dreams give us bulbs and screens rather than oil wicks, and that is a small test of the method. The lists were written for flames, but the Qur'an's picture is about light that guides, so the reading carries over to a lamp of any kind, and we would not make a different rule for a bulb. What does change the dream is what happens to the light: is it steady, who lit it, and what did it show.

If your lamp failed or would not light, that detail may be the mind's own worry as easily as a message, and the Sunnah's plainest question applies: first ask what kind of dream it was. Only after that does the table become useful.
