Default Question on lucid interval?

In epidural hematoma (as regard to lucid interval),it's mentioned that the victim after trauma immediately becomes unconscious, then gains consciousness and again becomes unconscious.
Can anybody pls explain what is the reason for initial unconsciousness (ie unconsciousnesss immediately after trauma) and what is the cause of gaining consciousness in between two unconsciousness. My simple understanding is that the patient remains conscious until the hematoma expands to such a point that brain structures become compressed (the classic lucid interval). But, I am not able to understand what leads to immediate unconsciousness and what makes the regain of consciousness?Thanks.

Default Hematoma

Well it makes sense that they lose consciousness at first! Imagine getting hit in the head really hard! Your brain bounces around and you might even have a concussion. You wake up, feel fine as this arterial bleed is quickly expanding, and then boom, you're out again.

The loss of consc. Initially is just because of head trauma (I.e cerebral commotion) "the brain it just been shaken to the bone"
