do you meditate and balance your chakra's? if the flow of energy in your body is unobstructed you'll have an easier time with magic, as well as your third eye will help you deal with spirits. don't focus on it alone, it's a bad idea to focus on one charka only. one being too open or too close can cause distress in your life. a third eye thats too open will cause migraines and extremely vivid imagination sometimes to the point where you can't tell if you imagined something.
there's also some teas you could try, but speak with your doctor to see if you're not allergic to anything. as well, look into crystals and stones, some have magical properties which will help you with spirits. furthermore there are times where it's easier to speak with spirits as the veil between the two worlds grows thicker and thinner throughout the year. as well, spirits go through phases of active and inactive. it's different for each one, some go through a weekly cycle, others yearly. the spirits in my home are all different, Rori is more active in may and october, and rather dormant through the winter months. this little girl spirit [whom i've yet to speak with] normally play in the hallway in the evenings, more-so in the fall than summer and winter. [so far] and i've know spirits to always be at the same energy, mostly because they conserve it, never over active or inactive.
