Car's battery, Booth, Dwarves and mystery

It is night. I'm in a stall based event where the business I work for has a stall. After a while I go back to my car. my step cousin comes and somehow takes the car back to the stall to use the second battery I have to power off something. She was smiling and good but isn't giving me enough time to react to it. I don't go to the event. Instead I chill where I am and after sometime I head to the stall. My visions goes full screen of my boss and me thinking if they know or not that I was working remotely being away from the stall in the night open ground stalls. When I arrive, I see the event is about to conclude, the car is there but the dual battery is completely disconnected from the car and on a table powering something. I'm surprised ! and I can't find my step cousin ! I'm frustrated and as I look for her or at this stage anyone to put it back together. I somehow see a dwarf who tells me that he knows someone that could be expert enough to re connect the battery to the car and to go with him. I embark and leave the event, as I reach the top of the mountain, picture of my mum or her herself being by my side and talking to me in flashes of images. I reach the pinnacle of a green mountain with not one dwarf but 6 dwarves. I look and I see a rigid downhill of rock climbing and tiresome paths to a house down the valley. I'm contemplating to not proceed further and wanting to go back, flashes of my mum is sending good vibes and a sense of comfort of staying. as I looked back as the dwarves proceeding and rock climbing down, after some time I made a decision to proceed and go and find this person. Next, I am the door of this house, All dwarves also enter and spread out around the house. I realise the house is more like a lab with many doors and it looks super abandoned. Dark scary rooms with the dwarves moving in the background. I see broken chairs, dirty places and some blood around. I tell the dwarves how messed up everything is and they nod with me but no one has an answer. One room, has a body of a doctor. I found a weird looking pill on his table. A dawrf is now telling me to grab it and we quickly rush out of that haunted house. The dwarves start scattering into the wilderness and fade out. I'm realizing there is a smaller house right next to this one. I'm heading now heading inside. I'm thinking of finding neighbors to tell them about what I found, but i find a decapitated body on the floor. I rush out. It's almost dusk, I better head back to my car... and climb all those rocks again.
