Explanation:

For the first question: Hallucinogens are psychoactive drugs that alter perception, cause visual hallucinations (like seeing geometric shapes), and can induce feelings of detachment from one's body, which matches Thomas's symptoms. Depressants slow bodily functions, stimulants increase arousal, and withdrawal is a reaction to stopping a drug, not a drug class.
For the second question: Serotonin is a neurotransmitter that regulates mood, hunger, sleep, and arousal. Dopamine is linked to reward and motivation, glutamate to learning and memory, and norepinephrine to alertness and stress responses.

Answer:

1. Hallucinogen
2. Serotonin
