iirc, those were flashbacks of when he was first 'caught' (the sudden bright light from their flashlights, the men with helmets that had a glowing circle on it reaching out for him) & taken to the orphanage.
while it was ultimately for his benefit, Mori didn't know that & it definitely caused him significant trauma to find the world he knew changed overnight.
From the looks of that page(him having the nightmare)it looks like mori is locked up / caught in a rope cage/ net with something reaching for him while he’s trapped, wonder what it could mean Σ( ￣□￣||)
