Am i experiencing night terrors?

Hi, for about six months now I have been experiencing what I think are night terrors. I am told that I shoot straight up in bed screaming and petrified. I do remember some of the things that seem to scare me so much, I have had spiders above the bed, a stranger in the corner of the room (apparently im convinced he is going to kill me) but the worst one is when i think I have lost my son, he is only two and have woken by my partner frantically searching our room as I think he is lost, trapped or needs help. Can anyone tell me if they do think this sounds like night terrors? thanks
