Imagine being trapped in a grave that never lets you sleep. That is the chilling picture Transmetal paints in Tumbas De Insomnio. Over blistering guitars, the Mexican metal legends plunge us into a nightmarish cemetery where flames flicker, shadows writhe, and every breath tastes like fear. The tomb is not in the ground but inside the mind, and its walls are built from sleepless nights, guilt, and unending dread.
Through vivid images of "sinister hands" tearing faces and "black ink clouds" spilling rage, the song turns insomnia into a personal underworld. Light never reaches this place, so horror reigns unchecked while distant voices remind the tormented soul of past mistakes. In the end, the only escape hinted at is to "close the curtains" on these relentless thoughts and let someone else guide you toward peace. Tumbas De Insomnio is a raw, poetic warning: ignore your inner demons too long and your own mind can become a fiery grave that never lets you rest.
