Skull - skullhead - head

so i was traveling days ago and after i arrived in my house,in the past 2 days iv seeing imagery of skull,different shapes and colors,in the 2 days i had dreams in scenarios of death like watching the whole thing happening as a spectator…the skullhead * head* always appears in my mind before i sleep and then its always long dreams of horrific scenarios…is that a indicative of a certain spirit ?

I suspect some names but i wanted to ask it in the forum anyways.
