Remembrance spells...better to meditate and tap into the hazy memories. You can increase your memory by meditating everyday and going over as much of the day as you possibly can (in full detail). Then once a week going over as much of the details of the week as you possibly can. Its proven to enhance your recollection if practiced consistently.
Creativity spells are abundant. I've heard of a knot spell that helps writers block. When you untie one of the knots its metaphorically loosening the "block". I'm sure you could come up with one to suit your situation. Google can assist you with ideas.
Awakening the inner spirit is pathwork. Many different cultures have various ways, but it isn't one spell that does it. Its dedication and conditioning of the mind. The buddhist path to enlightenment is one way.
