To use a colander in a dream reveals the arrival of lawsuits and legal problems because of material issues. If the holes are tight these issues will be favorable to you; but if, on the contrary, they are wide you will end up losing everything you had won. Seeing other people using a strainer means that, in real life, they do not accept you as you are and that this attitude will make you suffer.
Do blind people dream?
Dreams in blind people depend on the nature of their blindness. Individuals who have born blind will not have visual dreams instead they have night mares, most of them revolving around their challenges faced during the day. They experience dream through their sensory inputs like touch, smell, noise and emotions. People who were blinded after birth can experience visual dreams based on the visions or images that they have seen.
Types of sleep
There are two types of sleep that most of the humans undergo - REM and NREM. REM refers to the Rapid Eye Movement and NREM refers to Non-Rapid Eye Movement. Every individual will alternate these two types of sleep. Non-REM sleep will occur for a short period of time in the first stage of your sleep followed by the REM sleep. Dreams occur during the REM stage, where it lasts for 20 minutes. According to a researcher, J. Allan Hobson, dreams that occur in REM stage are usually forgotten when the individual wakes up. Studies conducted on patients during sleep shows that the frontal lobes in the brain, that are responsible for storing information, are inactive during the REM stage, which is the main cause for forgetting the dreams. Studies also show that this is the stage where you have the most intense dreams.
