"A lack of consent can include the victim's inability to say "no" to intercourse, due to the effects of drugs or alcohol."
He was unable to say no due to being in a hallucinatory state. Therefore it was rape.
He only regain the ability to say no after intercourse began.
It still rape if its unreported.
Also your argument is directly equivalent to "She couldn't say no, but her body was saying yes"
A date rapist might use it to justify their crimes.
