Sleeping in a place such as very narrow rooms or low bunk beds or in a position where you are facing a wall or propped up on your pillow can often lead to dreams with a suffocation or drowning theme as you respond to your environment subconscious. Eating right before going to sleep stimulates brain activity that can also cause a person to have nightmares.

Some people believe that all these things are manifestations of the anxieties that the stress they experience imposes on them psychologically.
Other reasons why nightmares occur can be due to psychological issues such as post-traumatic stress disorder or the stress of a recent upsetting experience where the person continues to relieving traumatic events while sleeping.
