Is it possible to dream while under anesthesia?
Conclusions: Dreaming during anesthesia is unrelated to the depth of anesthesia in almost all cases. Similarities with dreams of sleep suggest that anesthetic dreaming occurs during recovery, when patients are sedated or in a physiologic sleep state.
Can you dream when under anesthesia?
Our findings suggest that there are two types of dreams associated with anesthesia. The first are rare “near-miss awareness” dreams, and the second, which are much more common, are “recovery” dreams that occur during emergence from anesthesia. Both can be identified in this study.

What does your mind do under anesthesia?
Anesthetic drugs cause brain circuits to change their oscillation patterns in particular ways, thereby preventing neurons in different brain regions from communicating with each other. The result is a loss of consciousness—an unnatural state that he compares to a “reversible coma”—that differs from sleep.

How fast do you fall asleep under general anesthesia?
The anaesthetic should take effect very quickly. You'll start feeling lightheaded, before becoming unconscious within a minute or so. The anaesthetist will stay with you throughout the procedure.

Is there a chance you won't wake up from anesthesia?
Two common fears that patients cite about anesthesia are: 1) not waking up or 2) not being put “fully to sleep” and being awake but paralyzed during their procedure. First and foremost, both cases are extremely, extremely rare. In fact, the likelihood of someone dying under anesthesia is less than 1 in 100,000.
Why do they tape your eyes shut during surgery?

How does anesthesia put you to sleep so fast?
General anesthesia drugs were shown to induce unconsciousness by activating a tiny cluster of cells at the base of the brain called the supraoptic nucleus (shown in red), while the rest of the brain remains in a mostly inactive state (shown in blue).
Why do you not dream under anesthesia?
While under general anesthesia, you are in a drug-induced unconsciousness, which is different than sleep. Therefore, you will not dream. However, if you are under a nerve block, epidural, spinal or local anesthetic, patients have reported having pleasant, dream-like experiences.
Is the brain active during anesthesia?
The neurons are still firing, but the signal loses its complexity. A better understanding of how this works could make surgery safer, but many anesthesiologists don't use an EEG to monitor their patients. That bugs Emery Brown, who does monitor his patients' brain patterns when they are under.
Are you fully asleep with propofol?
"You feel alert, unlike with [the anesthetic] pentothal, which left patients feeling really worn out and hungover," Dombrowski says. "But while propofol induces sleep, it's not a clean, clear sleep."

What happens if you say something bad under anesthesia?
Anesthesia won't make you confess your deepest secrets
Rest assured, even if you do say something you wouldn't normally say while you are under sedation, Dr. Meisinger says, “it's always kept within the operating room. We know the patient is under extra medications and it's not a concern to us at all.”

Coming out of general anesthesia is not the same sensation as waking up from a good night's sleep.
