Perhaps some blue topaz will help - I have often used it to dispel bad dreams, with great effect. Also I agree about smudging and cleansing...it might also help to keep a dream diary beside your bed, so if you wake up at 4 a.m. with weird dreams, you can note them down - writing them can sort of "flush" them from your system for a time.
Myself when I begin to note massive energy changes, I swap from the stone I have been wearing, especially if I have been wearing it for a while, and choose something more soothing and grounding - or wear none at all, to sleep...
I have also often noted that springtime changes in my inner body clock can keep me strung up and awake, or having odd dreams, for weeks...
As a last resort, you can change your bedroom furniture around; if you are becoming increasingly sensitive, sometimes moving the bed to point in a different and calmer direction can help. I believe behead pointing south is the usual recommendation...anyways, I am no expert, but these are things that have worked for me in the past. Hth, and I hope you find relief!
