Dream reports hallucinations

Psychiatric The US FDA has stated that post-marketing cases of neuropsychiatric events have been reported for montelukast and zafirlukast [105 ]. The events included agitation, aggression, anxiousness, dream abnormalities, hallucinations, depression,... 

A few reporters have eaten the dream fish and described their strange effects. The most famous user is Joe Roberts, a photographer for the National Geographic magazine. He broiled the dream fish in 1960. After eating the delicacy, he experienced intense hallucinations with a science-fiction theme that included futuristic vehicles, images of space exploration, and monuments marking humanity s first trips into space. 

Pentazocine is contraindicated in the treatment of patients with acute myocardial infarction because of cardiovascular stimulation. Psychotomimetic side effects, such as hallucinations, bizarre dreams, and sensations of depersonalisation, occur in about 6-10% of patients. They are more common in elderly patients, in those who are ambulatory, and when doses above 60 mg are given. Nausea occurs in approximately 5% of patients although vomiting is less common. Other commonly reported side effects are dizziness and drowsiness. The risk of physical dependence is low. 

There are some reports by users that methadone use may cause hallucinations. While it is well known that heroin users often describe a dream-like mental state when using heroin, this effect is rarely seen in people who use methadone. The reason behind this is probably due to methadone s slower onset of action and reduced level of intensity. Likewise, while users of heroin and other harder narcotics sometimes report feelings of acute anxiety, especially when first using the drug, users of methadone rarely report these psychological effects. 

Repeated low-dose administration of OP compounds can produce symptoms and signs that are not seen after single exposures to the same doses. For example, subjects given dally injections of DFF reported the additional symptoms of insomnia, excessive dreaming, emotional lability. Increased libido, paresthesias, visual hallucinations, and tremor (90) and prolonged administration in animals induces sensorimotor neuropathy. 

The psychoactive properties of ibogaine and related compounds were studied by Naranjo (33,142), who reported that patients described the psychic state produced by ibogaine ( 300 mg) as similar to a dream state without loss of consciousness. Ibogaine-induced fantasies [often described as a movie run at high speed or slide show (7)] were reported as rich in archetypal contents, involving animals and/or the subject with or without other individuals. These fantasies were easy to manipulate by both the subjects and the psychotherapist (33,142). At higher doses, ibogaine appears to produce visual and other hallucinations associated with severe anxiety and apprehension (101,144,145). 

There have been several reports that some species of fish are psychotogenic in that ingestion can cause delirium, mental disorder or hallucinations. Indeed one of the sea chub family, Kyphosus fuscus, reputedly causes nightmares and is subsequently referred to in certain regions of the Pacific as the "dream fish". 

The most important adverse effects of efavirenz involve the CNS. Up to 53% of patients report some CNS or psychiatric side effects, but fewer than 5% discontinue the drug for this reason. CNS symptoms may occur with the first dose and may last for hours. More severe symptoms may require weeks to resolve. Patients commonly report dizziness, impaired concentration, dysphoria, vivid or disturbing dreams, and insomnia. Episodes of frank psychosis (depression, hallucinations, and/or mania) have been associated with initiating efavirenz. Fortunately, CNS side effects generally become more tolerable and resolve within the first 4 weeks of therapy. 

In another randomized, double-blind, placebo-controlled trial, suvorexant showed significant improvements on the co-primary end points of sleep efficiency on night 1 and at the end of week 4 Suvorexant was found to be weU-tolerated with the most frequent side effects including dose-related increase in somnolence (drowsiness), dizziness (4.9%), abnormal dreams (4.9%), headaches (4.9%), upper respiratory tract infection (3.3%), and urinary tract infection (3.3%). Increased levels of alanine aminotransferase were also observed, all of which occurred in a dose-dependent manner. All reports of increased alanine aminotransferase were considered to be mild and resolved spontaneously. One patient reported hypnagogic hallucinations at a dose of 80 mg. There were no withdrawal effects or rebound insonmia. Thus, a clear advantage of suvorexant over previous insomnia medications is the low potential for addiction or dependence. ...
