Somewhat obscure; “roof/house” with the idea of indoors above and “be like” acting phonetically as vanish – so vanishing light indoors, as in the evening. Alternatively may be a combination of indoors and moon (i.e. a miscopying of the below radical) – hence the idea of little light (like from the moon) indoors or vanishing light, as you would find in the evening.
