Sleepwalking, also known as somnambulism or noctambulism, is a phenomenon of combined sleep and wakefulness. It is classified as a sleep disorder belonging to the parasomnia family. It occurs during slow wave stage of sleep, in a state of low consciousness, with performance of activities that are usually performed during a state of full consciousness. These activities can be as benign as talking, sitting up in bed, walking to a bathroom, consuming food, and cleaning, or as hazardous as cooking, driving a motor vehicle, violent gestures and grabbing at hallucinated objects.Although sleepwalking cases generally consist of simple, repeated behaviors, there are occasionally reports of people performing complex behaviors while asleep, although their legitimacy is often disputed. Sleepwalkers often have little or no memory of the incident, as their consciousness has altered into a state in which memories are difficult to recall. Although their eyes are open, their expression is dim and glazed over. This may last from 30 seconds to 30 minutes.Sleepwalking occurs during slow-wave sleep (N3) of non-rapid eye movement sleep (NREM sleep) cycles. It typically occurs within the first third of the night when slow-wave sleep is most prominent. Usually, it will occur once in a night, if at all.
Bufotoxins are a family of toxic steroid lactones or substituted Tryptamines of which some may or may not be toxic. They occur in the parotoid glands, skin and poison of many toads (genus Bufo) and other amphibians, and in some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain 5-MeO-DMT, bufagins, bufalin, bufotalin, bufotenin, bufothionine, dehydrobufotenine, epinephrine, norepinephrine, and serotonin. Some authors have also used the term bufotoxin  to describe the conjugate of a bufagin with suberylarginine.The toxic substances found in toads can be divided by chemical structure in two groups:

bufadienolides, which are cardiac glycosides (e.g., bufotalin, bufogenin)
tryptamine-related substances (e.g., bufotenin)Toads known to secrete bufotoxin include the following:
Bufo alvarius
Bufo americanus
Bufo arenarum
Bufo asper
Bufo blombergi
Bufo boreas
Bufo bufo
Bufo bufo gargarizans
Sclerophrys gutturalis (syn. Bufo gutturalis)
Bufo formosus
Bufo fowleri
Rhinella marina (formerly Bufo marinus)
Bufo melanostictus
Bufo peltocephalus
Bufo quercicus
Bufo regularis
Bufo valliceps
Bufo viridis
Bufo vulgaris

Extraction
Extract from the skin of certain Asian toads, such as Bufo bufo gargarizans and Bufo melanostictus, is often found in certain Chinese folk remedies. The Pharmacopoeia of the Peoples Republic of China (ChP) considers the two species valid sources of toad venom (Chinese: 蟾酥; pinyin: Chánsū; Latin: bufonis venenum), and requires the dry product to contain at least 6% of cinobufagin and resibufogenin combined by weight. The extract is obtained by squeezing the parotoid glands of caught, washed toads for a white venom and drying; the final dried venom is usually brown, with a chunk or flake form. Human poisoning
Toad‐venom poisoning is rare but can kill.
