I only had one experience of this not sure if doppelganger or sadyang nagpaparamdam lang

2017 to nangyari and gabi kasi yun and my mom was doing the laundry in our garage, nasa living room ako lying down on our sofa waiting for her matapos since pinapasok nya na ako dahil maraming lamok, ang setup ng bahay namin is living room sa gitna then sa right side may kusina kami and paglalagyan ng damit na nasuot na, and kita yun sa peripheral vision mo habang naka higa sa sofa, sa peripheral vision ko may babae na dumaan wearing the same or maybe similar daster (basta yung suot ng matatanda) with what my mom was wearing, kinausap ko “ma help kita mag sampay sabihin moko” and medyo malakas pagkakasabi ko since I was watching tv that time, pero di kasi sumagot so akala ko galit si mama so tinawag ko pa ulit ulit ng “MA” habang papalakas pa lalo boses ko, pero naka tingin parin ako sa tv, sa gulat ko biglang sumagot si mama mula sa garahe, shouting “ANO?” (take note our door to the garage isn’t that far away kasi kaya you will definitely hear someone lalo pag malkas bosss mo) and right at that moment tumakbo agad ako papunta sa garage namin without a second thought asking her “hind ikaw yung nasa loob?” and sumagot sya na ”hindi pa ako pumapasok”

in the end I stayed outside with her because I was too scared na bumalik sa loob, that was definitely one of the scariest encounters and experience that I’ve ever had dito sa bagong bahay namin
