They live amongst us

Paranoia-inducing tales of covert invasion. This might be alien infiltration or they might come from... elsewhere. Basically anything that might keep David Icke up awake at night (hmm I should probably add "V" in there too).

So the key elements are infiltration, subversion, stealth colonisation and human disguise/mimicry, with the invaders hiding in plain sight.
