When I have a dream, and feel the taste of a food without the presence of the input signal, this means that my brain is able to make new arrangements from my memory?

Exactly! When you experience sensations like taste, sound, or touch in a dream, your brain is indeed creating new arrangements from memory. Here's how that works:
Memory and Sensory Experiences: Your brain stores memories of sensory experiences—like the taste of your favorite food, the smell of a flower, or the sound of a particular song. These memories are encoded as patterns of neural activity.
Dreams and Memory Activation: During dreams, especially in the REM (Rapid Eye Movement) phase of sleep, your brain can spontaneously activate these stored patterns. Even without any external sensory input, the brain can recreate the experience by triggering the same neural pathways that were active during the actual experience.
Synthesis of Experiences: In a dream, your brain doesn't just replay memories like a recording. It often combines, rearranges, and synthesizes elements from various memories, creating entirely new experiences. For example, you might taste a food you've never eaten before, or see a place that doesn't exist, made up of familiar elements from your memory.
Perception Without Input: Since your perception of sensory experiences during a dream is based on the brain's internal activity rather than external input, it shows the brain's powerful ability to generate vivid sensory experiences using memory alone.
This ability of the brain to create new sensory experiences from memory is a testament to its creative and reconstructive nature, highlighting how perception is as much about what the brain does as it is about the sensory input it receives.
