Some time ago , I was having a depresion and each time I've tried to sleep , a paralysis like feeling begin to take over me and i was feeling deing/being pulled in the image/vision in my head , despite my all efforts . Only by fighting very hard I succeeded to escape . This happened 3 times .

1st : It was about a cruising ship . I "know it " that if i will walk on it i will die

2nd : a dark tunnel - like hallway , with a dark skinned woman , in black clothes

3rd : a door open to an infinite prery

Can you help me to understand what was about ?

Thank you for your help .
