I've been having this... thing, it's not a big problem, but I'm curious about it. When I'm LDing I can perfectly remember the task I wanted to do or many other things, like memories of things I've done, etc.. But when I try to remember how my bedroom looks like, or my house, or certain appearance of things from waking life, I simply fail to remember or need great effort to do so. It's quite strange, like some dream-Alzheimer. Is there anyone with the same situation?
