Dreams spiral into the depth of the subconscious
We all need dreams. They have performed experiments where people were not allowed to dream because they interrupted the sleeper’s REM sleep. When they were allowed to go to sleep again without their REM sleep being interrupted, they made up for all the REM sleep they had missed by dreaming much more than they would have otherwise.
People with extreme psychological disorder or serious physical illness/malfunction do not dream. Marijuana, and alcohol to a lesser extent, block dream memory. Otherwise, everyone dreams. They just forget that they had a dream. The problem is not that they are not having dreams, the problem is that they cannot access their memory to recall dreams.
Surprisingly, people who wake up several times during the night may actually have more dreams. This is because for the dream to be remembered, it has to be transferred from short-term memory to long-term memory. This transfer takes place best when you are awake. So as long as you go back to sleep, waking up lightly several times at night may actually help you remember dreams.
