Venous bleed beneath the dura.

Explanation:
A venous bleed beneath the dura describes a subdural hematoma. It occurs when bridging veins between the dura and the arachnoid are torn, allowing venous blood to collect slowly under the dura. This bleed often presents gradually—headache, confusion, and sometimes focal deficits that can progress as the hematoma enlarges, especially in older adults or after minor head trauma. It’s a bleeding injury, not a pressure state by itself, and it’s distinct from conditions like status epilepticus (a prolonged seizure) or an aura (a sensory phenomenon before seizures or migraines).
