Other triggers may include:
- Mental stress
- Sleeping on the back
- Not having a regular sleep schedule
Episodes of ISP last from a few seconds to 1 or 2 minutes, often upon waking up from rapid eye movement (REM) sleep. REM sleep is when dreaming occurs. During ISP episodes, the person is unable to move or speak, but is aware of their surroundings. Breathing is not affected. These spells end on their own or when the person is touched or moved. In rare cases, the person may have dream-like sensations or hallucinations, which may be scary to them.
Hallucinations involve sensing things such as visions, sounds, or smells that seem real but are not. These things are created by the mind.Read Article Now Book Mark Article

In most cases, isolated sleep paralysis occurs so rarely that treatment is not needed. If the cause is known, for example, due to lack of sleep, correcting the cause by getting enough sleep often resolves the condition.
Sometimes, medicines that prevent REM during sleep are prescribed.
In persons with mental health conditions, such as anxiety, medicine and behavioral therapy (talk therapy) to help treat the mental health condition may resolve sleep paralysis.
When to Contact a Medical Professional
Discuss your condition with your provider if you have repeated episodes of ISP. They may be due to a medical problem that needs further testing.
