Remember the past spell

Light the light blue candle and imagine every thought floating towards you. Imagine them getting into your brain. Then look through your thoughts, and meditate. Once you start to feel like you've left your physical body, light the black candle. Do it quickly, so you don't leave your body forever. Now, imagine grabbing everything you need, and releasing everything else. Keep the memories and facts you want, but let the rest disappear. Once you have the memory you want, blow out the candles.
