Bright light sucking water and splashing with 2 legged hairy spider like monsters with wet black eyes

I was camping near a lake with a fellow scout.  I was awakened by splashing noises and water smells.  I looked out my tent door and saw a bright light gliding over the lake sucking up the water.  I was curious and frightened.  I laid face down and watched the light move over the water.  I started to worry about it and tried to wake up my tent partner. I could not wake him from his sleep and moved back towards the tent door but stopped.  I saw hairy 2 legged monsters.  I backed away from the tent door but could still see their images because the light was now closer.  I don't remember much more except that I have unending dreams of being pulled into the lake and emerging inside a cavern under the lake.  There was air, but it was hard to breathe it and I could see moving shadows.  The inside of the cavern had some kind of light source. In my dream I pulled out my scout flashlight with the rubber seal and point it toward the shadows and see spider like creatures, ! but hairy with tall thin legs. My light bothers them; I don't know why the light is an irritant.But, they move to my left and right as though they try to surround me. My flashlight dims over time and now I can see their wet black eyes. I hold back my tears and try to shout but I can't hear myself. Exhausted and with little light left they stick me with their pointy legs and smother my breath. I always wake up the same way I did that same morning after, soaked with sweat or lake water; I can't tell which.  I am scared to death every night I sleep, because I know they come in my dreams and I can't stop them.  I must tell you that I see myself like them in the mirror on occasion only to second look myself and see me normal again. I believe I was abducted but can't prove it. I was just a boy then and now I am in my 50's and still I am bothered with this horrible dream.  10 years ago I had a tumor removed from my body.  It was attached to my stomach. It weighed about a pound and! was about the size of a small orange.  The doctor said it was! an unus ual size and sent it to the lab for biopsy. That lab was flooded and the tumor was lost.  I have always wondered if that tumor was a spider sack?  I guess I will never know. If anyone has had similar dreams, I'd like to know?  I do have these red splotchy spots on my legs that my doctor says is a rash.  I have had them for decades. These spots end at the knee. Maybe some one else form your index has the same and we could share.  I am old fashioned when it comes to computers. And I'm too embarassed to let anyone know this fact, so I hope this is as good as your "cut and paste".
