A Strange Dream Do you get them after Reading Books??

Finally Got round to Picking up my H.P Lovecraft book "At the Mountains of Madness" for “2014 Horror's Best Books Reading Challenge” On Goodreads. And already the strange dream's have Begun. Had a strange dream I was trapped by some men in Park That had a Massive lake.
The Lake was dark and Mist was setting off from it, I was on the Bank trying to run away, When I looked Over and saw The massive Back of a Black water serpent Rise from the water then
Submerge once More. In my panic I jumped into a wooden Row boat and Then a horse came to sniff me and the Boat! and pushed me in to the water with its Self! But the water Monster got it and turned the boat over landing me in the shallows of the water Were I there ran and hid in a cove in the Banks.
Then A man walked by pushing an other in front of him by gun Point! And I put my finger to my mouth to say “Shhhst” Don't tell him I'm there and he told him. I screamed and woke up... I have no reverence If this is to do with reading the start of H.P Lovecraft or the book I’ve just finished By “Mark Dice” but none the less was such a vivid Dream.
has anyone else had strange dreams from reading Books?
