Sleep Is the 12th House; Rahu There Is the Nodal Version
Rahu does not invent insomnia by existing. It colors sleep when it occupies the 12th or joins the 12th lord. The Moon is the other factor.

The bed is the 12th
Sleep is the 12th house, and Rahu in the 12th is the placement people call a sleep dosha. Rahu there is traditionally read as unusual dreams, restless privacy, and sometimes residence far from home. The Moon is the mind that either settles or watches the night. A Moon joined to Saturn can feel heavy at night without Rahu being in the 12th at all. If your sleeplessness is the question, name the 12th lord and see whether Rahu aspects or joins it. If Rahu is in the 10th, your nodal problem is career, and the night may be fine. Calling every Rahu a sleep dosha empties the word of a house.
Not a diagnosis
A restless 12th is a symbol. A sleep disorder is a medical fact a chart must not certify or treat. This page will not list symptoms as proof, and it will not offer a cure. Rahu mahadasha, 18 years, makes a 12th-house Rahu loud for a long time. People then believe the dosha is permanent. The loudness is the dasha. Ketu in the 12th, the other node, is quieter and more inward, with Rahu in the 6th. That chart's nights and its conflicts are arranged differently. Know which node is in the bed house. The remedy lists that treat both nodes as one sleep curse are not reading.
What you may change and what you may not
You may not move Rahu out of the 12th. You may notice that a 12th-lord antardasha is the season of broken rest and that a later antardasha of a strong Moon or a strong lagna lord is quieter. You may keep ordinary hours, which suits Saturn if Saturn also aspects the Moon, and you may see a doctor if the nights are a health problem. Pearls and Rudraksha do not treat sleep. If the 12th lord is Mercury, the restlessness may be mental sorting, buddhi that will not stop, which is Mercury's nature in that house. Read Mercury then, not a generic Rahu video. The reason, when the chart has one, is occupancy of the 12th. The reason is not the existence of a node somewhere in the sky.
