Can You Remember Your Dreams? A Detective Mystery for kids 9-13: 29 Puzzles, 4 Ciphers, and the Real Brain Cells That Erase Your Dreams Every Single Night. Secret Code Activity Book for Kids 8–12 (PDF)

Can You Remember Your Dreams? — A Screen-Free Cipher Mystery for Kids 9–13 (Bestie Knows, Case #2)

Try to remember a dream from last week. Go on. We'll wait.

...Got one? Same as everybody. By breakfast, almost every dream you've ever had was deleted on purpose — and the suspect is still hiding inside your skull, working the night shift.

Bestie Knows: Can You Remember Your Dreams? is a 29-puzzle detective story for kids 9–13. Every puzzle decodes one piece of a real neuroscience mystery. The last page has the reveal. The kid does the work. The tiny pack of brain cells with an unpronounceable name takes the fall.

QUIT EVERY ACTIVITY BOOK BY PAGE 10?

This one isn't a workbook. It's a mystery. Every chapter ends on a cliffhanger. Real ciphers — Caesar, Atbash, substitution — plus word scrambles, word searches, mazes, and acrostics, all stitched into one detective arc about why your brain erases the dreams you had last night.

THREE WAYS TO READ IT

Solo in your room. Race a sibling. Or tonight's family adventure: tear chapters apart, divide the work, meet at the back for the answer key. Designed for either hand — lefty-friendly answer lines on every puzzle page.

BUILT ON REAL NEUROSCIENCE

This is the actual science. REM. The hippocampus. Sleep paralysis. And MCH neurons — the brain cells real scientists discovered with mice and tiny brain lasers (yes, really) that delete dreams every single night. Body humor + real research is what gets a kid 9–13 to actually finish a book. We put both in this one.
