Looking for spiritual experience is probably what is getting in your way. Expectation can destroy the progress.
Being bored is just a step on the path to cultivation, your mind is just getting in your way and not letting you integrate yourself with yourself. In other words, don't seek and just be and that will lead to natural spiritual experiences in time. In Zen Buddhist speak, the mastery of meditation is Void, boredom is the illusion the mind casts to keep you attached to desire.
If you are not seeking to be a Zen Master then creative visualization may help. Pathworking, such as through the Qabalistic Tree of Life or to the Underworld to meet a spirit guide, can be fun. All you need is a creative memory or a recording to take you through the process. Yoga Nidra is also an excellent way to enhance meditation that involves utilizing all five senses that puts your body to sleep at the same time keeping your mind awake.
