White Light Warning Of Second Sinister Visit

This happened around 3 years ago, and affected me so badly I have only spoken to 2 people about the events since, and it is only now that I am intrigued and looking for explanations!

I was asleep alone in my flat, when an amazingly bright white floated into my room and around to the side of my bed, I felt an overwhelming urge that it was encouraging me to get up and leave my room but I felt it was tricking me and something bad would happen if I did. So I stayed put. I could see visions of my hand turning my door handle and could hear a distant weak breathy voice saying "go, leave" but still I stayed.

I'm not sure how long that lasted but suddenly the energy of the room felt like it changed, my door flew open and I heard loud footsteps running the same route the light had moved around my bed. I suddenly felt freezing cold and paralyzed I tried to move but felt pinned down. What happened next is hard for me to describe, it felt as if this thing was raping me. I felt so much pressure on my lower body and anything I tried to move, I couldn't, and this felt like forever. I would go through periods where I felt warm again as if I could move, but as soon as I tried to I felt the pressure and cold again. Eventually I felt warm for a while and, though sure this it had left I lay still by choice until morning incase it returned.

Retrospectively the first thing felt inherently good, as if it was warning me of the second thing and trying to get me to leave, oh how I wish I had listened. The second thing felt violent, aggressive and pure evil.

I hope I have included all the appropriate details, I am quite new to this all as until that night I was a complete skeptic, but unfortunately I cannot find anything to explain this so I fear my explanation lies in the paranormal!
