Cover art for Chloroform lyrics by Porcupine Tree

i think the is about a man, who is schizophrenic or something.. the first four lines describes a disease, he could be in a hospital ("motorcade") and they search the disease ("under the radar") but can't find it.. maybe because it's not a physical disease.. the rest of the lyrics he talks about himself.. he's maybe a tranny and "Shards of light come down/Stillness in the air" his secret came out, somebody saw him on his feminine side. the he talks to himself, to banish this side, cause he has kids and so on..
