Hi, welcome to LD4all

The hallucinations can come in several forms. The visual ones are nice because they make it easy to just step into your dream, but the non-visual can work just as well. Some people mention that when they get these weird feelings, they just allow themselves to sink into their beds or float out of their real body and into a dream body.

You simply have to ignore it. You’re going to get really annoying signs from your mind and body asking you to change positions. You have to just let it go. The more you think about it, the more you impede yourself.
Having answered those questions, I would like to suggest you try to WILD later at night, about 5-6 hours after you first fall asleep. In this state, you will fall asleep much faster and easier. It can be harder to concentrate, but is generally the best time for WILD.
Also, check out our Knowledge Base. There are some great articles there that will help out a lot, such as the WILD tutorial and the WILD FAQ. Lastly, I would strongly encourage you to experiment with other techniques. WILD is very alluring because of its grand promises, but can be very difficult to master. Many new dreamers get discouraged when they feel they aren’t making progress. DILD and RCILD are great ones to supplement your WILD attempts with.
Anywho, best of luck 
. Just let us know if you have any more questions.
