I do see thing out the corner of my eye yes but its not a bad feeling i get when its around . I tend to start medition with lying down and work with my breathing putting my mind in to a state of pure blankness (only way i can think to discribe it) like im standing in a dark room. Then i just let my mind wonder.
the pictuers/moments have been climbing a ladder in to clouds to see a hand reach down that i cant grab. Allow this may not seem + it felt it.
Some times thought i feel what ever is around me is linked to my past live's and i get the feeling for the old and out dated things in life during and after i meditate.
Also have very close links to dogs during medition but sadly they are not my totem animal. And they are not angry agressive beasts unless they have to be hehehe
worst moment ie most - one was a red and black shaped shadow with green flaring eye's that towered over me i got round this by making my self/engery get bigger than that till it was so small it was not a fear and more of an intrest but it was still freaky for 5 mins or what felt like 5 mins
tho hopefully not to sound mad at one point i thought there were lots of things following me around not so much now but some times i still feel like that from time to time
as for fear in my own mind yes i have some of it but its more around my past lifesand the feeling im not doing what i'm ment to be doing ie what i have done in ever other past life one line that pops to mind when i think of this is "your on holiday"
i have no clue what some of this means or if its just the rambling of a young mind but its intresting all the same
