Males experience erections throughout the night, which are called nocturnal penile tumescence (NPT). These erections occur about every 90 minutes and usually last for 20-30 minutes. NPT is a normal physiological process and is not necessarily related to sexual arousal or dreams. It is important for the overall health of the penis as it helps to keep the tissues oxygenated, which can prevent erectile dysfunction.
