Everything we see, hear, taste, smell and touch is remembered by our brain, and put into what we might call a brain file. When we read a book, watch a television show or video, listen to music, eat some ice cream or pet a soft rabbit, it is all recorded in our files. We call those files our memories. We dream about many different things. When we go to sleep, our brain begins to take bits and pieces of memories and put them together into a dream.
Some dreams are fun or silly, while others can be scary.
Most dreams do not make a lot of sense, because our brain just took little pieces from a bunch of different memories. People do many things in their dreams that they really could or would never do, like fly or jump off a building, or swim and breathe under water. Some people believe dreams all have a deep meaning. Others think dreams are just jumbles of thoughts. There may be some truth to both ideas.
